Versuchsvorschrift
3-(6-Chloro-1,6-dihydro-pyridazin-4-yl)-N-methyl-benzamide (1 eq, 2.46 mmol, 610 mg) is dissolved in a solution of NH3 (7N, 20 ml) in EtOH and heated at 160° C. in a sealed tube for 48 h. The solvent is then removed in vacuo. The reaction mixture is purified by flash column chromatography eluting with 8:2:0.5 DCM/MeOH/NH3 to give 3-(6-Amino-1,6-dihydro-pyridazin -4-yl)-N-methyl-benzamide as a brown solid; [M+H]+=229
