Reaction Steps

5-Chloro-1-{3-[4-(3-nitrophenyl)-1-piperazinyl]propyl}-3,4-dihydrocarbostyril (3 g) was dissolved in 100 ml of ethanol, 2 ml of concentrated hydrochloric acid was added, and catalytic reduction was carried out at 3 atmospheres in the presence of 1.5 g of 5% palladium-carbon. The catalyst was then filtered off, the filtrate was concentrated under reduced pressure, and the residue was recrystallized from ethanol to give 2.5 g of 1-{3-[4-(3-aminophenyl)-1-piperazinyl]propyl}-5-chloro-3,4-dihydrocarbostyril as colorless needles.
