Reaction Steps

To a microwave flask was added 4-(6-bromo-5-(4-chlorophenyl)-2-((2-methyl-6-(trifluoromethyl)pyridin-3-yl)methyl)-3-oxo-2,3-dihydropyridazin-4-yl)benzonitrile (105 mg, 0.187 mmol), pyridine (10 ml) and anhydrous hydrazine (60 mg, 1.87 mmol). The reaction was subjected to microwave at 200° C. for 30 min. After this time the solvent was removed to give 4-(5-(4-chlorophenyl)-6-hydrazinyl-2-((2-methyl-6-(trifluoromethyl)pyridin-3-yl)methyl)-3-oxo-2,3-dihydropyridazin-4-yl)benzonitrile as a yellow solid. The material was used in the next step without further purification.
