PROCEDURE
实验过程
24.0 g (75.4 mmoles) of ethyl 3-amino-4-(2-(phthalimido)ethoxy)crotonate and 18.9 g (79.2 mmoles) of methyl 2-(2-chlorobenzylidene)acetoacetate in 64 ml of ethanol were heated under reflux for 20 hours. The reaction mixture was diluted with 56 ml of ethanol and was cooled to crystallise the product. 14.2 g (yield 70%) of 4-(2-chlorophenyl)-3-ethoxycarbonyl-5-methoxycarbonyl-6-methyl-2-(2-phthalimidoethoxy)methyl-1,4-dihydropyridine were obtained.
