PROCEDURE
实验过程
Heating a solution of 7.6 g of 3-nitrobenzaldehyde, 5.0 g of acetylacetone and 9.2 g of 3-pyrrolidino-3-aminoacrylic acid ethyl ester in 50 ml of ethanol for 2 hours yields 2-pyrrolidino-6-methyl-4-(3-nitrophenyl)-5-acetyl-4,5-dihydropyridine-3-carboxylic acid ethyl ester of melting point 130°C (isopropanol/ether). Yield: 44% of theory.
