Dialkyl 4-(3-aminophenyl)-1,4-dihydro-2,6-dimethylpyridine-3,5-dicarboxylates 1 were transformed into alkyl 4-(3-(((2-benzoylamino-2-methoxycarbonyl)ethenyl)amino)phenyl)-1,4-dihydro-2,6-dimethyl-pyridine-3,5-dicarboxylates 4 and with 2,2-disubstituted-1-dimethylaminoethenes 7 into dimethyl 4-(3-(((2,2-diacyl- or 2-acyl-2-alkoxycarbonyl)ethenyl)amino)phenyl)-1,4-dihydro-2,6-dimethylpyridine-3,5-dicarboxylates
将4-(3-氨基苯基)-1,4-二氢-2,6-二甲基吡啶-3,5-二羧酸二烷基酯1转化为烷基4-(3-((((2-苯甲酰基氨基-2-甲氧基羰基)乙烯基)氨基)苯基)-1,4-二氢-2,6-二甲基吡啶-3,5-二羧酸酯4和2,2-二取代-1-二甲基氨基乙烯7变成二甲基4-(3-(((2,2-二酰基或2-酰基-2-烷氧基羰基)乙烯基)氨基)苯基)-1,4-二氢-2,6-二甲基吡啶-3,5-二羧酸酯8及其乙基甲基类似物9。
