Procedure

A solution of methyl 4-oxo-1-[3-(trifluoromethyl)phenyl]-1,4-dihydropyridazine-3-carboxylate (1.007 g, 3.38 mmol) in ammonia (7 N in MeOH, 12 mL, 84 mmol) was heated under microwave heating conditions at 100° C. for 5 min. After that time the reaction was cooled to room temperature and concentrated to give a yellow solid. This was recrystallized from EtOAc to give 0.613 g (64%) of 4-oxo-1-[3-(trifluoromethyl)phenyl]-1,4-dihydropyridazine-3-carboxamide as colorless crystals.
