The resulting compound of formula XXVI generally is not isolated, but utilized directly in the next step. 
     In step (z), a compound of formula XXVI, is reacted with an alkali metal azide, for example, sodium azide, in the presence of a polar inert solvent, for example, dimethylformamide, N-methylpyrrolidinone, dimethylsulfoxide or the like at a temperature of from about room temperature to 100° C. until azide formation is complete. The resulting compound of formula VIIIa can be isolated utilizing conventional methods, for example, chromatography or the like. This transformation generally proceeds with inversion of chirality at the carbon atom of XXVI bearing Q. 
     In step (y), a compound of formula XXVI is reacted with an amine anion equivalent to give an intermediate which can be deprotected to give an amine of formula Va.

When a compound of formula XXVI is chiral, this transformation will generally proceed with inversion of configuration at the carbon atom bearing Q in a compound of formula XXVI. 
     In step (v), an alcohol of formula XXIII is oxidized to a carbonyl derivative of formula XXIV. Reagents which are useful for this transformation include chromium based oxidizing reagents, for example, pyridinium chlorochromate. A preferable procedure is described in K. Omura and D. Swern, Tetrahedron 1978, 34, 1651, which involves dissolution of a slight excess of an acid halide, for example, oxalyl chloride in an inert halocarbon solvent, for example dichloromethane, cooling to a reaction temperature of from -50° C. to -80° C., addition of excess dimethyl sulfoxide, stirring for 0.25 to 0.5 hours, addition of one equivalent of an alcohol of formula XXIII, after an additional 0.25 to 0.5 hours, addition of excess triethylamine while maintaining the reaction temperature at from -50° C. to -80° C., and allowing the reaction mixture to warm for 0.5 to 1 hour before quenching with water and excess inorganic base to produce a carbonyl derivative of formula XXIV. 
     In step (x), a carbonyl derivative of formula XXIV is reacted with an amine of formula XXV to form a Schiff&#39;s base which is reduced in the presence of an appropriate reducing agent to produce an amine of formula Va in either a one step or two step process. For example, a compound of formula XXIV is treated with a large excess of an amine of formula XXV and an equivalent amount of a weak organic acid, for example acetic acid, in the presence of a reducing agent such as sodium cyanoborohydride in a suitable solvent, preferably a lower alkanol, for example methanol, at room temperature until the starting material is consumed. Alternatively, an amine of formula XXV and a carbonyl derivative of formula XXIV heated together in aromatic solvent in an apparatus fitted with a water separator until water formation is complete. The resulting Schiff&#39;s base can be hydrogenated over a suitable catalyst, preferably Raney nickel, at a hydrogen pressure of from one to five atmospheres to give a compound of formula Va. When R 6  is not hydrogen and R 5  is chiral, the resulting amine Va may be enriched in one diastereomer over the other. For example, when R 5  is a chiral benzyl group, for example, R-alpha-methylbenzyl, and R 6  is lower alkyl, for example, methyl, the compound of formula Va may be diastereomerically enriched, and the chiral benzyl moiety may be removed, for example by hydrogenation over palladium on carbon to give an enantiomerically enriched amine of formula Va, R 5  =hydrogen and R 6  =lower alkyl. The compounds of formula Va can be isolated utilizing conventional methods, for example, extraction followed by distillation, crystallization of their acid addition salts, chromatography or the like.

The resulting compounds of formula Va can be isolated utilizing conventional methods, for example, distillation, crystallization of their acid addition salts, chromatography or the like. This transformation proceeds without alteration of the chirality of the carbon atom bearing the azido group in a compound of formula VIIIa. ##STR23##

     In step (dd), a compound of formula XXIX is hydrolyzed to an amine of formula Vb. This process is advantageously carried out where R 15  is 2-nitrobenzyl by catalytic reduction of the nitro group for example over palladium on carbon at one atmosphere hydrogen pressure, and heating of the residue in the absence of solvent or in the presence of a solvent, for example acetic acid. The resulting compounds of formula Vb can be isolated utilizing conventional methods, for example, distillation, crystallization of their acid addition salts, chromatography or the like. ##STR24##

The resulting compounds of formula XXXIV can be isolated utilizing conventional methods, for example, crystallization, chromatography or the like. 
     Compounds of formula XXXIV in which R 6  is non-hydrogen, and R 11  is hydrogen, may be resolved into their enantiomers by conversion to salts of chiral, enantiomertically pure amines, for example cinchonine, brucine, alpha-methylbenzylamine or the like. The pure diasteromeric salts are obtained by fractional crystallization from an appropriate solvent, for example a lower alkanol. The chiral, enantiomerically pure acids of formula XXXIV, R 11  =hydrogen may be recovered from their salts by conventional means, for example extraction from an aqueous, acidic solution. 
     In step (ff), a heteroaromatic carboxaldehyde of formula XXXI, is reacted with a (carboxyalkylidene)triarylphosphorane of formula XXXII in a suitable solvent, for example tetrahydrofuran, dichloromethane, methanol or dimethylsulfoxide, to give a compound of formula XXXIII. The resulting compounds of formula XXXIII can be isolated utilizing conventional methods, for example, crystallization, distillation, chromatography or the like. 
     In step (gg), a compound of formula XXXIII is hydrogenated over a suitable catalyst, for example, palladium on carbon or platinum oxide, in a suitable solvent, for example, a lower alkanol, at a hydrogen pressure of from one to five atmospheres until the theoretical amount of hydrogen is taken up to give a compound of formula XXXIV. 
     In step (hh), a compound of formula XXXIV is converted into an amide of formula XXXV using conventional techniques for the conversion of carboxylic acids and esters into the corresponding primary amide. For example, a compound of formula XXXIV, R 11  =hydrogen may be converted to the corresponding acid chloride by treatment with thionyl chloride and then treated with an excess of ammonia to give a compound of formula XXXV. Alternatively, a compound of formula XXXIV, R=lower alkyl, may be converted into a compound of formula XXXV by treatment with excess ammonia, optionally in the presence of co-solvent, for example, a lower alkanol, at a temperature of from -33° C. to room temperature. The reaction may be run in a pressure vessel when appropriate. 
     In step (ii), a compound of formula XXXV is treated with a reducing agent, for example borane in tetrahydrofuran at a temperature of from room temperature to the reflux temperature of the solvent for 4 to 24 hours or until reduction is complete to give a compound of formula Vc. The resulting compounds of formula Vc can be isolated utilizing conventional methods, for example, by destruction of the excess reagent with a lower alkanol, followed by treatment with a mineral acid, for example, hydrochloric acid, basification, evaporation of the solvent and extraction of the product into a suitable organic solvent, for example, dichloromethane and purified by distillation, chromatography or the like. 
     In step (jj), an acid of formula XXXIV, R 11  =hydrogen, which may be obtained from the corresponding ester by hydrolysis, is subjected to conditions leading to a Curtius rearrangement in the presence of a lower alkanol. In a preferred procedure, an acid of formula XXXIV (R=hydrogen), is treated with one equivalent of diphenylphosphoryl azide in the presence of a proton acceptor, for example triethylamine or the like, and an excess of a lower alkanol or a phenol to give a compound of formula XXXVI. The resulting compounds of formula XXXVI can be isolated utilizing conventional methods, for example, crystallization, chromatography or the like. 
     In step (kk), a compound of formula XXXVI is treated with an excess of a mineral acid in water and optionally an addition co-solvent, for example a lower alkanol, at a temperature of from room temperature to 100° C. or with a strong base in water, optionally in the presence of a co-solvent, for example a lower alkanol at a temperature of between 60° C. and 100° C. to form a compound of formula Vd. The resulting compounds of formula Vd can be isolated utilizing conventional methods, for example, crystallization of their acid addition salts, distillation, chromatography or the like. ##STR25## 
     wherein Het, A&#39;, R 7&#39;   and R 15 , are as previously described, and R 6&#39;   is lower alkyl. 
     In Reaction Scheme X, step (ll), an alcohol of formula XXIIIa is reacted with a nitrile of formula XXVIII in the presence of a mineral acid, for example sulfuric acid, and water at a temperature of from -20° C. to room temperature to give a compound of formula XXIXa. The compound of formula XXIXa can be isolated by conventional means, for example chromatography, crystallization or the like. 
     In this Reaction Scheme, step (dd), is the same as step (dd) in Reaction Scheme X to give a compound of formula Vd. The compound of formula Vd can be isolated by conventional means, for example, chromatography, crystallization or its acid addition salts, distillation or the like. ##STR26## 
     wherein Het, A*, R 5 , R 6  and R 7  are as previously described, R 17  is a chiral moiety, for example, a bonded chain lower alkyl or lower alkyl substituted with one or two groups selected from hydroxy, lower alkoxy, lower alkylcarbonyloxy, perfluoroalkyl, or aryl. 
     In Reaction Scheme XIII, step (mm), those compounds of formula V which are chiral may be resolved into their enantiomers by conversion to amides of chiral, enantiomerically pure acids using common techniques of peptide coupling. For example, a chiral amine of formula V may be coupled with a chiral, enantiomerically pure acid, for example (R)-mandelic acid, in the presence of a suitable coupling reagent, for example, a dicyclohexylcarbodiimide optionally in the presence of a promoter, for example 1-hydroxybenzotriazole in a polar, aprotic solvent, for example dimethylformamide to give an amide of formula XXXVII. Amides of formula XXXVII may be separated into pure diastereomers by fractional crystallization, chromatography or the like. 
     In step (nn), enantiomerically pure compounds of formula V may be recovered by hydrolysis of diastereomerically pure amides of formula XXXVII, for example with an aqueous mineral acid at a temperature of from 60° C. to 120° C. 
     The compounds of formula I can form acid addition salts with inorganic or organic acids. Thus, they form pharmaceutically acceptable acid addition salts with both pharmaceutically acceptable organic and inorganic acids, for example, with hydrohalic acids, such as, hydrochloric acid, hydrobromic acid, hydroiodic acid, other mineral acid salts, such as, sulfuric acid, nitric acid, phosphoric acid, perchloric acid or the like, alkyl and mono-aryl sulfonic acids such as, ethanesulfonic acid, toluenesulfonic acid, benzenesulfonic acid, or the like, other organic acids such as tartaric acid, maleic acid, citric acid, salicylic acid, ascorbic acid and the like. Non-pharmaceutically acceptable acid addition salts of compounds of formula I can be converted into pharmaceutically acceptable acid addition salts via conventional metathetic reactions whereby the non-pharmaceutically acceptable anion is replaced by a pharmaceutically acceptable anion; or alternatively, by neutralizing the non-pharmaceutically acceptable acid addition salt and then reacting the so-obtained free base with a reagent yielding a pharmaceutically acceptable acid addition salt. 
     The compounds of formula I exhibit activity as platelet activating factor (PAF) antagonists and are, therefore, useful in disease states characterized by excess platelet activating factor or for the prevention and treatment of cardiovascular diseases, pulmonary diseases, immunological disorders, inflammatory diseases, dermatological disorders, shock or transplant rejection. 
     The useful activity of the compounds of formula I can be demonstrated by the following procedures: 
     BINDING ASSAY 
     (a) Assay 
     The binding assay was done in 400 μl polyethylene microcentrifuge tubes (Beckman) containing 50 μl of an oil mixture of 2 parts Siliconol AR200 (Serva): 1 part Silicone Fluid (Arthur H. Thomas). Buffer, standards, or analogs (150 μl total volume) were added to the tubes. Radiolabelled  3  H-PAF (50 μl) was then added to the tubes. The reaction was started by the addition of 50 μl of dog platelets (2×10 7  platelets). The tubes were capped, inverted several times to mix, and incubated for 10 minutes at room temperature. The platelets were separated from the incubation mixture by centrifuging 1 minute in a Beckman Microfuge B centrifuge. The tip of the microfuge tube was cut off, and the platelets were washed out of the tip with 200 μl of 50% methanol (Burdick and Jackson). Aquasol (NEN, 10 ml) was added and the radioactivity in the samples was determined using an LS 8100 Beckman liquid scintillation counter linked to a Techtran tape recorder. Data was processed through an in-house computer system. Alternatively, radioactivity was determined using a Searle Mark III liquid scintillation counter linked to a Iso-Data microprocessor. Results are set forth in Table I. 
     (b) Preparation of Platelets 
     Blood was collected from anesthesized or unanesthesized dogs into 50 ml plastic centrifuge tubes containing 3.8% sodium citrate as the anticoagulant (1 volume of citrate/9 volumes of blood). The red cells were removed by centrifugation for 15 minutes at 600 rpm (100-125 g) at room temperature. An aliquot of the supernatant platelet rich plasma (PRP) was saved for cell counting and the remainder was acidified by pH 6.5 with 0.15M citric acid. The platelet pellet was obtained after a 10 minute centrifugation at 2000 rpm (1000 g) at room temperature. Washed platelets were prepared by resuspending the platelet pellet once with PBS containing 1 mM EDTA, centrifuging as noted, and then resuspending the platelets in 0.1% BSA-PBS. An aliquot of the washed platelets was counted. Platelets used for binding assays were diluted to 2×10 7  platelets/assay tube (4×10 8  platelets/ml). Platelet counting was done using a Royco Cell-Crit 921. 
     PAF Induced Bronchoconstriction Assay 
     Male animals (Hartlet Strain, 400-500 g) were anesthetized with urethane (2 g/kg, i.p.). Each animals&#39; trachea was cannulated and the guinea pigs were respirated using a Harvard small animal rodent respirator (3.0 cc stroke volume, 40 breaths per min.). Tracheal pressure was recorded from a cannula inserted in the trachea and connected to a Statham Pressure Transducer. 
     The jugular vein was cannulated for administering compounds. Spontaneous breathing was arrested with succinylcholine (1.2 mg/kg, i.v.) administered 2 minutes prior to intravenous injection of platelet activating factor (PAF). Since propranolol has been shown to enhance bronchoconstrictor responses, all animals were pretreated five minutes prior to challenge with propranolol (0.1 mg/kg, i.v.). 
     For, the intravenous testing, the guinea pig is given a 5-minute pretreatment with propranolol at a dose of 0.1 mg/kg intravenously. The test compound is administered with a 1 minute pretreatment prior to intravenous challenge with PAF. The animal is then challenged with a 1.0 μg/kg intravenous dose of PAF and the change is tracheal pressure is measured. 
     For the oral testing, the procedure includes a 2-hour pretreatment period with the test compound administered through an oral gavage tube. Propranolol or succinylcholine and PAF are administered intravenously, and the change in tracheal pressure measured. 
     The change is tracheal pressure is determined by subtracting the steady state baseline achieved after administration of succinylcholine from the peak bronchoconstriction seen after challenge with PAF. The mean is calculated for each test compound and compared to the mean of the control animals to give the percent inhibition of bronchoconstriction. The standard error is calculated as the standard error of the mean. 
     PAF INDUCED PLATELET COUNT DECREASE 
     Male Hartley guinea pigs weighing between 500 and 900 grams were fed standard guinea pig chow and tap water ad libitum. PAF was solubilized in ethanol and stored as a 2 mM stock solution at -70° C. The stock solution of PAF was diluted to 1 pM in Tris buffer pH 7.4 and 0.1% BSA for all experiments. 
     (a) Intravenous Procedure 
     Guinea pigs were anesthetized with urethane (1.6 g/kg, i.p.). A catheter (PE50) was introduced into the right carotid artery for withdrawing blood. A second catheter PE10) was introduced into the jugular vein for injecting drugs and for administering the PAF challenge (75 ng/kg, i.v.). A control blood sample was obtained and platelets were counted in a whole blood platelet analyzer. PAF was then given and blood samples were taken 15, 30, and 60 seconds after the challenge for platelet counts. Fifteen minutes later, selected concentrations of the test compound were solubilized in DMSO and injected intravenously into a group of 4-6 animals. Only one concentration of antagonist was used in each animal group. Fifteen minutes after drug injection, blood samples were taken before and 15, 30, and 60 sec after the PAF challenge, and analyzed for platelet number. 
     (b) Oral Procedure 
     Animals were anesthetized with sodium pentobarbital (35 mg/kg, i.p.) and the caritoid artery and jugular vein were cannulated as described above. The cannulae were exteriorized at the base of the neck and the animals were allowed to recover. At least 18 hours after surgery, conscious unrestrained guinea pigs were used in the experiment. The animals were challenged two time with PAF (120 ng/kg, i.v.); the first to establish a consistent response to PAF and the second to serve as a control for the PAF challenge. Blood samples were taken before and 15, 30, and 45 seconds after PAF challenge and platelets were counted. Thirty minutes after the control PAF challenge, the animal were orally dosed with either gum acacia or the test compound. Animals were then challenged with PAF at 1, 3, 5, and 24 hours after the administration of the drug. 
     DATA ANALYSIS AND STATISTICS 
     The % change, i.e., the difference in platelet number before and after PAF challenge was calculated by: ##EQU1## 
     Statistical significance (p 0.05) of the difference between the mean PAF control and mean drug treated activity was determined with paried Student&#39;s t-test. 
     The compounds of formula I also have Thromboxane Synthase (TXA 2  Syn.) Inhibitory Activity, which can be demonstrated as follows. 
     TXA 2  SYNTHESIS INHIBITION 
     Thromboxane Synthase inhibitory TAX 2  syn. activity is measured by following the conversion of  14  C-thromboxane A 2  (TXA 2 ) using microsomal fractions from human platelets as enzyme source. In the aqueous incubation medium, the TA X 2  decomposes rapidly into TXB 2 . The amount of TXA 2  syn. is adjusted so that under the conditions of the assay approximately 80-90% of the substrate, PGH 2 , is converted to product in control tubes. To prepare  14  C-PGH 2 ,  14  C-AA(50-60 mCi/mmole; Rose Chem.) is incubated with sheep seminal vesicular gland microsomes for 1.5 min. at 37° C. and then the  14  C-PGH 2  is extracted with diethylether, purified on columns of Sephadex LH-20 or silicic acid, and stored in acetone at -70° C. Incubations are done as follows. Sufficient  14  C-PGH 2  to yield a final substrate concentration of 10 μM (˜30,000 cpm) is added to the incubation tubes and then the acetone is removed under nitrogen. The tubes are placed in an ice bath and then 215 μl of ice cold phosphate buffered saline, 10 μl of ethanol (control) or of test drug in ethanol, and 25 μl of the microsomal suspension are added with mixing in that order as rapidly as possible. The tubes are incubated at 22° C. for 2 minutes, the reaction is stopped and then the radioactive products and the unconverted PGH 2  are extracted and analyzed by thin layer chromatography. The amount of  14  C-PGH 2  converted to products is analyzed by thin layer chromatography. The amount of  14  C-PGH 2  converted to products was used as a measure of TXA 2  synthase activity. Inhibitors were tested initially at a concentration of 100 μM. IC 50  values were calculated by linear regression analysis of successive 10 fold dilutions of the test compound concentration. Results are provide in Table II.

     A compound of formula I, an enantiomer thereof or a salt thereof or a composition containing a therapeutically effective amount of a compound of formula I, an enantiomer thereof or a salt thereof can be administered by methods well known in the art. Thus, a compound of formula I an enantiomer thereof or a salt thereof can be administered either singly or with other pharmaceutical agents, for example, antihistamines, mediator release inhibitors, methyl xanthines, beta agonists or antiasthmatic steroids such as prednisone and prednisolone, orally, parenterally, rectally, or by inhalation, for example, in the form of an aerosol, micropulverized powder or nebulized solution. For oral administration they can be administered in the form of tablets, capsules, for example, in admixture with talc, starch, milk sugar or other inert ingredients, that is, pharmaceutically acceptable carriers, or in the form of aqueous solutions, suspensions, elixirs or aqueous alcoholic solutions, for example, in admixture with sugar or other sweetening agents, flavoring agents, colorants, thickeners and other conventional pharmaceutical excipients. For parenteral administration, they can be administered in solutions or suspension, for example, as an aqueous or peanut oil solution or suspension using excipients and carriers conventional for this mode of administration. For administration as aerosols, they can be dissolved in a suitable pharmaceutically acceptable solvent, for example, ethyl alcohol or combinations of miscible solvents, and mixed with a pharmaceutically acceptable propellant. Such aerosol compositions are packaged for use in a pressurized container fitted with an aerosol valve suitable for release of the pressurized composition. Preferably, the aerosol valve is a metered valve, that is one which on activation releases a predetermined effective dose of the aerosol composition. 
     In the practice of the invention, the dose of a compound of formula I or a salt thereof to be administered and the frequency of administration will be dependent on the potency and duration of activity of the particular compound of formula I or salt to be administered and on the route of administration, as well as the severity of the condition, age of the mammal to be treated and the like. Oral doses of a compound of formula I or a salt thereof contemplated for use in practicing the invention are in the range of from about 25 to about 1000 mg per day, preferably about 25 to about 250 mg either as a single dose or in divided doses. 
     The geometric and diastereomeric isomers encompassed by formula I can be separated by conventional means, for example, chromatography, crystallization and the like. It is noted, however, that the separation in most instances is done at a earlier stage in the synthesis of the compounds of formula I. 
    
    
     The examples which follow also further describe the invention. All temperatures given are in degree centigrade unless otherwse stated.

     (a) From (R,S)-alpha-methyl-3-pyridinebutanamine 
     A solution of 281.5 g of 1,3-dicyclohexylcarbodiimide in 400 ml of dimethylformamide was added to a stirred solution of 204 g of (R,S)-alpha-methyl-3-pyridinebutanamine, 198.4 g of (R)-mandelic acid and 209.75 g of 1-hydroxybenzotriazole in 1400 mL of dimethylformamide, maintained at -10° C. during the addition by intermittent cooling with a dry ice-acetone bath. After stirring at -5° for 4 hours, then at room temperature overnight the mixture was recooled to 0° C. for 2 hours. The precipitated solids were filtered and washed in turn with cold dimethylformamide (2×150 mL) and ethyl acetate (2×300 mL). This material, a mixture of 1,3-dicyclohexylurea (DCU) and the less soluble (R*,R)-mandelamide, was dispersed in 2 L of 1N HCl and stirred at room temperature for 3 hours. The undissolved solids (DCU) were removed by filtration and were washed with 200 mL of dilute HCl and with water. The filtrate was basified and the resulting material was collected by filtration, washed with water and dried in vacuo to give 64.4 g of [R-(R* R*)]alpha-hydroxy-N-[1-methyl-4-(3-pyridinyl)butyl]benzeneacetamide, the (R*,R)-mandelamide, mp 144°-146° C.; [α] D   25  -27.8° (c, 1.0, MeOH). 
     The original mother liquors and washings were concentrated to dryness under reduced pressure and the residue was dispersed in 2 of 1.5N NaOH and extracted with dichloromethane (1×2 L; 2×1 L). The organic extracts were washed with in turn with 1N NaOH (2×800 mL) and then in turn with 1N HCl (1×1.5 L; 2×750 mL). The combined acidic aqueous layers were basified with 350 mL of 10N NaoH and extracted with dichloromethane (1×2 L; 2×1 L). The extracts were dried (K 2  CO 3 ) and evaporated to give 280 g of mandelamide, rich (˜3:2) in the (S*,R)-diastereomer. The residue was crystallized three times from 2-propanol to yield 74.1 g of the less soluble (R*,R)-mandelamide, mp 144°-146° C. 
     The mother liquors from the final two crystallizations were combined, evaporated and the residue crystallized twice from 2-propanol to give an additional 7.2 g of the (R*,R)-diastereomer, mp 143°-145° C. The total yield of [R-(R*,R*)]-alpha-hydroxy-N-[1-methyl-4-(3-pyridinyl)butyl]benzeneacetamide, obtained in three crops, was 145.6 g (78.5%). 
     All remaining mother liquors were combined, evaporated and dried to give 198 g of mandelamide rich in the (S*,R)-diastereoisomer. This material was reserved for further processing, particularly to serve as a potential source of (S)-alpha-methyl-4-pyridinebutanamine. 
     (b) Via an enatioselective process from 5-(3-pyridinyl)-2-pentanone

Water was removed from the reaction as it was formed using a Dean-Stark trap. The cooled solution was hydrogenated over 70 g of Raney Nickel at room temperature and 50 psi. When approximately 50% of the theoretical amount of hydrogen had been taken up, the reaction essentially stopped. The spent catalyst was removed and replaced with 70 g of fresh Raney Nickel and the hydrogenation was continued until the absorption of hydrogen ceased. After the catalyst was removed by filtration, the filtrate was washed with 250 mL of 1N sodium hydroxide solution, then was dried and evaporated to give 106 g of an oil. HPLC analysis of the product showed that the main component (˜68%) was [R-(R*,R)]-N-[1-methyl-(3-pyridinyl)butyl]-alpha-methylbenzylamine along with 13% of the related (S*,R)-diastereomer. 
     The above mixture (105 g) in 1 L of ethanol was hydrogenolysed over 21 g of 20% Pd(OH) 2  on charcoal (50° C.; 25 psi) for a total of 51 hours. After the catalyst was removed by filtration, the solvent was evaporated and the residue distilled to provide 33.6 g of alpha-methyl-3-pyridinebutanamine enriched in the (R)-enantiomer. 
     To a cooled (-5° C.) solution of 32 g of the above enriched amine, 33 g of 1-hydroxybenzotriazole and 31.22 g of (R)-mandelic acid in 350 mL of dimethylformamide, was added a solution of 44.26 g of 1,3-dicyclohexylcarbodiimide in 150 mL of dimethylformamide and the mixture was stirred at -5° C. for 18 hours. After the precipitated dicyclohexylurea was removed by filtration, the filtrate was evaporated and the residue dispersed in 300 mL of cold 2N sodium hydroxide. The resulting solids were removed by filtration, washed with dilute sodium hydroxide solution and with water and then dissolved in 500 mL of 2N hydrochloric acid. The acidic solution was extracted with dichloromethane (3×150 mL) to remove neutral impurities, then was basified with 10N sodium hydroxide and extracted with dichloromethane (6×300 mL). The dried extracts were evaporated to give 55 g of residual solid. Crystallization of the product from ethanol gave 25.6 g of [ R-(R*,R)]-alpha-hydroxy-N-[1-methyl-4-(3-pyridinyl)butyl]benzeneacetamide, mp 141°-143° C. An additional 1.3 g of product, mp 141°-143° C., was obtained from the mother liquors.
