Versuchsvorschrift

1.9 Grams of 6-[1-oxo-3-(4-phenyl-1-piperidyl)propyl]-3,4-dihydrocarbostyril and 0.5 g of palladium black were dispersed in 80 ml of water and the dispersion was stirred under 2 atmospheric pressure of hydrogen gas at a room temperature for 5 hours. The reaction mixture was filtered for removing the palladium black and the mother liquor was concentrated under a reduce pressure then the residue thus obtained was crystallized by adding a small amount of ethanol then crude crystals thus obtained were collected by filtration and recrystallized from ethanol to obtain 1.4 g of 6-[1-hydroxy-3-(4-phenyl-1-piperidyl)-propyl]-dihydrocarbostyril in colorless plate-like crystals.
