Procedure

Into a 50-mL round-bottom flask, was placed a solution of 3-ethyl-1-phenyl-1H-indazol-6-ylboronic acid (1.4 g, 5.26 mmol, 1.00 equiv) in ethyl acetate (10 mL). To the resulting mixture was then added H2O2 (2 mL) dropwise with stirring at 0° C. The resulting solution was stirred for 2 h at 0° C. in a water/ice bath. The resulting mixture was concentrated under vacuum. The residue was applied onto a silica gel column with ethyl acetate/petroleum ether (1:10) to yield 3-ethyl-1-phenyl-1H-indazol-6-ol as a white solid. MS: 239 (MH+).
