Shibanuma, Tadao published the artcileSynthesis of optically active 2-(N-benzyl-N-methylamino)ethyl methyl 2,6-dimethyl-4-(m-nitrophenyl)-1,4-dihydropyridine-3,5-dicarboxylate (nicardipine), HPLC of Formula: 101-98-4, the publication is Chemical & Pharmaceutical Bulletin (1980), 28(9), 2809-12, database is CAplus and MEDLINE.
(+)- And (-)-nicardipine (I) were prepared from (-)- and (+)-1-ethoxymethyl-5-methoxycarbonyl-2,6-dimethyl-4-(m-nitrophenyl)-1,4-dihydropyridine-3-carboxylic acid (II). Resolution of II was carried out using cinchonidine and cinchonine. The vertebral vasodilating activity of (+)-I.HCl was about 3 times that of (-)-I.HCl.
