Reaktionsschritte

A stirred solution of 6-chloropyridazin-3-amine (18.4 g, 0.14 mol) and 2-bromo-1-(4-methyl-3-nitro-phenyl)ethanone (36.13 g, 0.14 mol) in acetonitrile (219 mL) is heated at reflux for 18 hr. The mixture is diluted with water (500 mL), stirred at room temperature for 1 hour and solids are collected by filtration to give the title compound (35.65 g, 88% yield). LCMS m/z=289.4 [M+H]+, tR=2.65 min.
