Reaction Steps

2-(2,3-Dihydroxy-propylamino)-4-(6,6-dimethyl-4-oxo-3-trifluoromethyl-4,5,6,7-tetrahydro-indazol-1-yl)-benzonitrile (1.7 g, 4 mmol, 1 eq), NaOH (806 mg, 20 mmol, 5 eq), and H2O2 (3 mL) were dissolved in EtOH-water (4:1) (40 mL). The mixture was microwaved at 120° C. for 15 min, then concentrated to dryness, and purified by flash chromatography, eluted by 10% MeOH in EtOAc to give pure 2-(2,3-Dihydroxy-propylamino)-4-(6,6-dimethyl-4-oxo-3-trifluoromethyl-4,5,6,7-tetrahydro-indazol-1-yl)-benzamide (0.52 g, 29% yield). LCMS (m/z): M+H=441.
