Reaction Steps

0.3 Gram of sodium metal is dissolved in 80 ml of ethanol and to this solution is added 3.6 g of 5-[3-(4-phenylpiperazinyl)propoxy]-3,4-dihydrocarbostyril, then 1.5 g of benzoyl chloride are added and the solution is heated for 5 hours under refluxing conditions. The reaction mixture is concentrated under reduced pressure to dryness. To the residue thus obtained is added water and the insoluble matter is collected by filtration, washed with ater and dried. The crude crystals are recrystallized from ligroin to obtain 3.9 g (yield: 86%) of 1-benzoyl-5-[3-(4-phenylpiperazinyl)propoxy]-3,4-dihydro carbostyril in the form of pale yellowish needle-like crystals with a melting point of 113° C.
