Procedure

1.5 Gram of 6-{1-oxo-4-[4-(4-nitrophenyl)piperazinyl]-butyl}-3,4-dihydrocarbostyril and 0.3 g of 5% palladium-carbon were dispersed in 150 ml of ethanol and catalytically reduced under 2 kg/cm2 of hydrogen gas for 5 hours. The reaction mixture was filtered and the mother liquor was concentrated under a reduced pressure. The residue thus obtained was recrystallized from methanol to obtain 0.7 g of 6-{1-hydroxy-4-[4-(4-aminophenyl)-1-piperazinyl]butyl}-3,4-dihydrocarbostyril in brown powdery crystals.
