실험 절차

A mixture of m-nitrobenzaldehyde, 2-(4-benzyl-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-benzyl-1-piperazinyl)ethyl methyl 2,6-dimethyl-4-(3-nitrophenyl)-1,4-dihydropyridine-3,5-dicarboxylate as a light yellow powder, m.p. 106°-108° C. (sintering). Yield 86.0%. IR(Nujol)cm-1 : 3325. NMR(CDCl3) δ: 2.33(6H,s, ##STR33## 3.46(2H,s,C6H5CH2 --), 3.61(3H,s,COOCH3), 4.14(2H,t,J=6,--COOCH2CH2 --), 5.09(1H,s,C(4) --H), 5.82(1H,s,NH).
