Reaction Steps
To a solution of 4-nitro-1H-indazole (0.500 g, 3.06 mmol) in acetone (0.4M, 7.5 mL) cooled to 0° C. was added KOH (0.258 g, 4.60 mmol). After 15 minutes at 0° C., (bromomethyl)benzene (0.400 mL, 3.37 mmol) was added. The reaction mixture was allowed to stir at ambient temperature overnight. The reaction mixture was concentrated under reduced pressure and the residue was purified by column chromatography (50% EtOAc/hexanes) providing 256 mg (33%) of the title compound.
