A process for the preparation of 2-(N-benzyl-N-methylamino)-ethyl-methyl-1,4-dihydro-2,6-dimethyl-4-(3-nitrophenyl)-3,5-pyridine dicarboxylate hydrochloride.

摘要

2-(N-benzyl-N-methylamino)-ethyl-methyl 1,4-dihydro-2,6-dimethyl-4-(3-nitrophenil)-3,5-pyridine-dicarboxylate hydrochloride is prepared by reation of 3-nitro-benzaldehyde, methyl 3-aminocrotonate and 2-(N-methylamino)ethyl acetoacetate and subsequent reaction with a benzyl halide in inert solvents.
