실험 절차

1.82 g (3.38 mmol) of 3-(3-phenyl-2-propene-1-yl) 5-(2-cyanoethyl) 4-(3-chlorophenyl)-2-dimethoxylmethyl-6-methyl-1,4-dihydropyridine-3,5-dicarboxylate was dissolved in 12.7 ml of acetone. 1.27 ml of 6 N hydrochloric acid was added to the obtained solution, and they were stirred at 0° C. for 6 hours. Acetone was evaporated under reduced pressure, and then water was added to the residue. After the extraction with chloroform, the organic layer was successively washed with a saturated aqueous sodium hydrogencarbonate solution and saturated aqueous salt solution, and then dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure and the residue was purified by the silica gel chromatography (hexane/ethyl acetate=3/1) to obtain the title compound.
