Reaction Steps

1-[1-(1-Benzyloxycarbonyl-2-pyrrolidinylcarbonyl)-4-piperidinyl]-3,4-dihydrocarbostyril (0.87 g) is dissolved in ethanol (20 ml) and thereto is added 5% palladium-carbon (0.1 g). The mixture is stirred at room temperature under 1 atm. under hydrogen atmosphere. After the completion of the reaction, the catalyst is filtered off and the filtrate is concentrated. The resultant is purified by silica gel column chromatography (solvent; dichloromethane:methanol=8:1) to give 1-[1-(2-pyrrolidinylcarbonyl)-4-piperidinyl]-3,4-dihydrocarbostyril (205 mg).
