Procedure

To a solution/suspension of 4-(6,6-dimethyl-4-oxo-3-trifluoromethyl-4,5,6,7-tetrahydro-indazol-1-yl)-2-(tetrahydro-pyran-4-ylamino)-benzonitrile (772 mg, 1.79 mmol, 1.0 eq) in 10 mL of 4:1 ethanol-dimethyl sulfoxide was added 1 mL of 1 M aqueous sodium hydroxide and 1 mL of 30% hydrogen peroxide. After 30 minutes the reaction mixture was diluted with water and extracted with ethyl acetate (4×). The combined organic layers were washed with brine, dried over sodium sulfate, filtered, and concentrated in vacuo to afford the title compound, 4-(6,6-dimethyl-4-oxo-3-trifluoromethyl-4,5,6,7-tetrahydro-indazol-1-yl)-2-(tetrahydro-pyran-4-ylamino)-benzamide (788 mg, 98%) as a tan solid: LC/MS (m/z): [M+H]+ 451.2.
