実験手順

1.1 g (2.9 mmol) 6-[2-(2,6-dichloro-pyridin-3-yl)-benzoxazol-6-yl]-5-methyl-4,5-dihydro-2H-pyridazin-3-one, 1 ml morpholine and 50 ml of ethanol are refluxed together for 3 h, then the solv. is eliminated by rotary evaporation i.V., the residue is stirred with water and filtered off. The crude product is recrystallised from aqueous isopropanol.
