Procedure
In 5 ml of ethanol were dissolved 500 mg of 2-[(E)-3-[4-(3-pyridylmethyl)phenyl]allyloxy]ethyl acetoacetate, 0.20 g of methyl 3-aminocrotonate and 300 mg of 3-trifluoromethylbenzaldehyde, and the resulting solution was subjected to reaction under reflux for 15 hours. Subsequently, the solvent was removed by distillation under reduced pressure, and the residue thus obtained was purified by a column chromatography [Wako Silica Gel C-200, eluant: chloroform:ethanol (100:1 by volume)] to obtain 660 mg (yield 72.8%) of pale yellow, powdery 3-[2-[(E)-3-[4-(pyridin-3-ylmethyl)phenyl]allyloxy]ethyl] 5-methyl 2,6-dimethyl-4-(3-trifluoromethylphenyl)-1,4-dihydropyridine-3,5-dicarboxylate.
