Versuchsvorschrift

8-Aminocarbostyril (15.47 g, 96.6 mmols) and bis(β-bromoethyl)amine hydrobromide (33 g, 106 mmols) were suspended in DMF and the suspension was stirred at 70° to 80° C. for 10 hours. After adding 5.1 g of sodium carbonate the reaction mixture was stirred at the same temperature as above for 7 hours. After distilling off the solvent under reduced pressure, methanol was added to the residue to crystallize. The crude crystals thus obtained were recrystallized from methanol-ether to give 5.1 g of 8-(1-piperazinyl)carbostyril hydrobromide, m.p. above 300° C., colorless scales.
