To a solution of ethyl 6-chloro-4-(3,5-dimethylphenylamino)pyridazine-3-carboxylate (104 mg, 340 μmol) in methanol was added ammonia in methanol (4.86 mL, 34.0 mmol) and stirred at 50° C. for 16 h. The mixture was concentrated to give 6-chloro-4-(3,5-dimethylphenylamino)pyridazine-3-carboxamide (90 mg, 325 μmol, 96%) as a brown solid, which was used directly without purification. 1H NMR (400 MHz, DMSO-d) δ ppm 10.84 (s, 1H), 8.72 (s, 1H), 8.08 (s, 1H), 7.12 (s, 1H), 6.98 (s, 2H), 6.98 (s, 1H), 6.93 (s, 1H), 2.30 (s, 6H); MS (EI/CI) m/z: 276.9 [M+H].
