실험 절차

8-Amino-3,4-dihydrocarbostyril (7.5 g, 46.2 mmols) and bis(β-bromoethyl)amine hydrobromide (15.9 g, 50.8 mmols) were suspended in methanol and the suspension was heated under reflux while stirring for 9 hours. After adding 2.5 g of sodium carbonate, the reaction mixture was further heated under reflux for 8 hours while stirring, and stirred on an ice bath for 1 hours. Crystals which precipitated were collected by filtration. The crude crystals thus obtained were recrystallized from methanol-ether to give 2.4 g of 8-(1-piperazinyl)-3,4-dihydrocarbostyril hydrobromide, m.p. above 300° C., colorless needles.
