PROCEDURE

实验过程

A mixture of 2-{[4-(2-chlorophenyl)-3-ethoxycarbonyl-5-methoxycarbonyl-6-methyl-1,4-dihydropyridin-2-yl]methoxy}thioacetamide (2.19 g) and 1-bromo-4-phthalimido-2-butanone (1.48 g) in ethanol (50 ml) was heated under reflux for 4 hours and then evaporated. The residue was triturated with ether/hexane and the resulting solid collected, recrystallised from methanol and dried to give 2-{[4-(2-chlorophenyl)-3-ethoxycarbonyl-5-methoxycarbonyl-6-methyl-1,4-dihydropyridin-2-yl]methoxymethyl}-4-(2-phthalimidoethyl)thiazole as a hemihydrate (1.73 g), m.p. 156°-157° C. Found: C,59.71; H,5.06; N,6.31. C32H29ClN3O7S.0.5H2O: requires C,59.58; H,4.80; N,6.51%.
