To a stirred solution of 4-hydroxyindazole (702 mg, 5.24 mmol) in DMF (10 mL) at ambient temperature under argon was added sodium hydride (231 mg of a 60% dispersion in mineral oil, 5.76 mmol). The mixture was stirred for 10 minutes and then benzyl bromide (0.622 mL, 5.24 mmol) was added via syringe. After stirring for 2 hours at ambient temperature, the mixture was quenched with ammonium chloride solution, the solvents were evaporated and ethyl acetate and water were added. The product was extracted into ethyl acetate and the organic solution was dried (Na2SO4) and evaporated.
