Procedure
2.0 Grams of 6-methylsulfonyloxy-7-[1-oxo-3-(4-phenyl-1-piperidyl)propyl]-3,4-dihydrocarbostyril and 0.5 g of palladium black were dispersed in 50 ml of ethanol and the mixture was catalytically reduced under 3 atmospheric pressure of hydrogen gas for 5 hours. The reaction mixture was filtered and the mother liquor was concentrated under a reduced pressure to obtain a residue. Then the residue was recrystallized from ethanol to obtain 1.1 g of 7-[1-oxo-3-(4-phenyl-1-piperidyl)-propyl]3,4-dihydrocarbostyril in colorless needle-like crystals.
