Versuchsvorschrift

A solution of 3-(4-cyclopropyl-piperazin-1-yl)-6-(3-nitro-phenyl)-pyridazine (3.60 g, 11 mmol) in ethanol (18 mL) was added to water (30 mL) and powdered Fe (1.86 g, 33 mmol). The mixture was stirred for 3 h at 80° C. The resulting mixture was filtered and the filtrate was extracted with CH2Cl2. The organic phase was washed with brine, dried (Na2SO4) and concentrated to give 2.32 g (71%) of 3-[6-(4-cyclopropyl-piperazin-1-yl)-pyridazin-3-yl]-phenylamine.
