Reaction Steps

A solution of 4-oxo-N-phenyl-1-[3-(trifluoromethyl)phenyl]-1,4-dihydropyridazine-3-carboxamide (0.153 g, 0.426 mmol), 1H-benzo[d][1,2,3]triazole (0.201 g, 1.69 mmol) and thionyl chloride (0.06 mL, 0.82 mmol) in methylene chloride (2 mL) was heated under microwave heating conditions at 80 watts of power for 10 min. After that time, the reaction was concentrated and the crude product purified by flash column chromatography (silica gel, hexanes to ethyl acetate) to give 0.114 g (58%) of 3-[1H-benzotriazol-1-yl(phenylimino)methyl]-1-[3-(trifluoromethyl)phenyl]pyridazin-4(1H)-one as a pale red solid that was used without further characterization.
