PROCEDURE

实验过程

A mixture of 2,3-dichlorobenzaldehyde, 2-(4-benzhydryl-1-piperazinyl)ethyl acetoacetate and methyl 3-aminocrotonate was worked up in isopropyl alcohol in the same manner as Example 1 to give 2-(4-benzhydryl-1-piperazinyl)ethyl methyl 4-(2,3-dichlorophenyl)-2,6-dimethyl-1,4-dihydropyridine-3,5-dicarboxylate as a light yellow powder, m.p. 84°-88° C. (sintering). Yield 31.6%. IR(Nujol)cm-1 : 3320, 1730, 1690.
