Procedure

A solution of methyl 4-oxo-1-[3-(trifluoromethyl)phenyl]-1,4-dihydropyridazine-3-carboxylate (1.019 g, 3.42 mmol) and hydrazine monohydrate (0.3 mL, 6.19 mmol) in ethanol (10 mL) was heated under microwave conditions for 10 min at 120° C. After that time, the reaction was cooled to room temperature and the product was collected by filtration and washed with cold ethanol to give 4-oxo-1-[3-(trifluoromethyl)phenyl]-1,4-dihydropyridazine-3-carbohydrazide (0.607 g, 60%) as bright orange crystals.
