実験手順
2.0 Grams of 5-(3-piperazinylpropoxy)-3,4-dihydrocarbostyril and 1.5 g of benzoyl chloride are mixed with 20 ml of pyridine and stirred at 50°-60° C. for 3 hours. The reaction mixture is concentrated under reduced pressure to dryness. The residue is converted into a hydrochloric acid-salt thereof, then recrystallized from methanol to obtain 5-[3-(4-benzoylpiperazinyl)propoxy]-3,4-dihydrocarbostyril hydrochloride in the form of colorless plate-like crystals with a melting point of 240° C. (decomp.).
