Procedure

179 mg (0.49 mmol) of mono(2-cyanoethyl) 4-(3-chlorophenyl)-2,6-dimethyl-1,4-dihydropyridine-3,5-dicarboxylate, 245mg (1.63 mmol) of 2-amino-N-phenylacetamide, 129 mg (0.67 mmol) of 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride and 11 mg (0.09 mmol) of 4-dimethylaminopyridine were stirred in 10 ml of dichloromethane at room temperature overnight. Ethyl acetate was added to the reaction mixture, and the product was washed with 1 N hydrochloric acid and then with a saturated aqueous sodium hydrogencarbonate solution. The organic layer was dried over anhydrous sodium sulfate and then concentrated under reduced pressure. The residue was purified by the silica gel chromatography (chloroform/methanol=100/1) to obtain the title compound.
