SYNTHESIS AND SOME PROPERTIES OF 5-ALKYLAMINO-2-(PHTHALIMIDOALKYL)-1,3-OXAZOLE-4-CARBONITRILES
5-Alkylamino-1,3-oxazole-4-carbonitriles containing a 2-phthalimidoethyl or 3-phthalimidopropyl substituent at position 2 of the oxazole ring were synthesized. In the reaction of 5-(morpholin-4-yl)-2‑(2-phthalimidoethy)l-1,3-oxazole-4-carbonitrile with hydrazine hydrate, 2-(2-aminoethyl)-5-(morpholin-4‑yl)-1,3-oxazole-4-carbonitrile is formed. In the case of the 3-phthalimidopropyl analog, the recyclization product 3-amino-2-(morpholin-4-ylcarbonyl)-6,7-dihydro-5 H -pyrrolo[1,2- a ]imidazole is formed. Authors: S. A. Chumachenko, O. V.
