실험 절차

150 mg (0.416 mmol) of mono(2-cyanoethyl) 4-(3-chlorophenyl)-2,6-dimethyl-1,4-dihydropyridine-3,5-dicarboxylate and 81.4 mg (0.499 mmol) of 3-(2-methoxyphenyl)-allylamine were dissolved in 10 ml of dichloromethane. 120 mg (0.624 mmol) of 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride and 63.7 mg (0.416 mmol) of 1-hydroxybenzotriazole were added to the obtained solution under cooling with ice, and they were stirred at room temperature for 2 hours. Dichloromethane was evaporated under reduced pressure. Ethyl acetate was added to the residue, 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 (dichloromethane/methanol=100/1) to obtain the title compound.
