<unk>  monohydrochloride is a slightly yellow to yellow crystalline substance. It is synthesized in several steps, the first involving the preparation of racemic 2,8-diazabicyclo4.3.0nonane which is then resolved using tartaric acid. A suitably derivatised quinolinecarboxylic acid is then introduced, in the presence of DABCO, followed by acidification to form<unk>  hydrochloride.
