Procedure
2.0 Grams of 6-[1-oxo-3-(4-phenylpiperazinyl)-propyl]-3,4-dihydrocarbostyril and 0.6 g of 5%-palladium carbon were dispersed in 80 ml of ethanol and stirred at a room temperature under 2 atmospheric pressure of hydrogen gas for 5 hours. The reaction mixture was filtered for removing the palladium carbon and the mother liquor was concentrated under a reduced pressure and the residue thus obtained was recrystallized from isopropanol to obtain 1.4 g of 6-[1-hydroxy-3-(4-phenyl-1-piperazinyl)propyl]-3,4-dihydrocarbostyril in colorless needle-like crystals.
