PROCEDURE

实验过程

In 70 ml of isopropyl alcohol saturated with ammonia were dissolved 5 g of 2-nitratoethyl acetoacetate and 2 g of 2-nitrobenzaldehyde. The solution was heated at reflux for 5 hours and then treated in the manner described in Example 1 to give 2.51 g of 2,6-dimethyl-4-(2-nitrophenyl)-1,4-dihydropyridine-3,5-dicarboxylic acid bis(2-nitratoethyl) ester.
