Procedure

233 mg (0.350 mol) of 4-(4-(3-chlorophenyl)-5-(3,3-diphenylpropoxycarbonyl)-2,6-dimethyl-1,4-dihydropyridine-3-carbonyl) piperazine-1-carboxylic acid-t-butyl ester was dissolved in 10 ml of dichloromethane. 5 ml of trifluoroacetate was added and stirred at room temperature for 2.5 hours. After concentration under reduced pressure, saturated aqueous sodium hydrogencarbonate solution was added and the reaction mixture was extracted with ethyl acetate. The organic layer was dried over anhydrous sodium sulfate and then concentrated under reduced pressure to obtain the title compound.
