Procedure

808 mg (1.46 mmol) of 4-(3-chlorophenyl)-2,6-dimethyl-1,4-dihydropyridine-3,5-dicarboxylic acid 3-(2-cyanoethyl) ester 5-(3,3-diphenylpropyl) ester was dissolved in 15 ml of methanol. 3 ml of 1 N aqueous sodium hydroxide solution was added and stirred at room temperature for 2 hours. After adding 2 N hydrochloric acid, methanol was evaporated under reduced pressure. Water was added to the residue, and solid matters were taken by the filtration, then washed with water and hexane/ethyl acetate (3/1) and dried under reduced pressure to obtain the title compound.
