Versuchsvorschrift

To a solution of 3-[6-(4-cyclopropyl-piperazin-1-yl)-pyridazin-3-yl]-phenylamine (400 mg, 1.36 mmol) in CH2Cl2 (25 mL) was added triethylamine (275 mg, 2.72 mmol). Then acetyl chloride (171 mg, 2.18 mmol) was added dropwise and the resulting mixture was stirred overnight at rt. The reaction was quenched with water (15 mL) and the phases were separated. The organic phase was washed with brine, dried (Na2SO4) and concentrated to give a crude product, which was recrystallized from MeOH. This afforded 201 mg (48%) of the title compound.
