实验过程
Boiling a solution of 12.5 g of 3-nitrobenzylideneacetoacetic acid methyl ester and 8.2 g of 3-amino-3-dimethylaminoacrylic acid ethyl ester in 100 ml of ethanol for 2 hours yields 2-dimethylamino-6-methyl-4-(3-nitrophenyl)-4,5-dihydropyridine-3,5-dicarboxylic acid 3-ethyl ester-5-methyl ester of melting point 95°C (isopropanol). Yield: 54% of theory.
