Reaction Steps

To a room temperature solution of 1-(5-allyl-4-chloro-5H-pyrrolo[3,2-d]pyrimidin-7-yl)-2,2,2-trifluoro-1-[1-(4-fluorophenyl)-1H-indazol-5-yl]ethanol (245 mg, 0.5 mmol, 1 equiv.) in 4 mL of acetone and 2 mL of water was added a solution of KMnO4 in 1 mL of water and 2 mL of acetone. After 3 hours, the mixture was filtered and the filter cake washed with acetone. The filtrate was concentrated and the residue diluted with water and extracted with EtOAc. The combined organic layers were dried, filtered, and concentrated in vacuo. The residue was purified by HPLC (5-85% CH3CN/water 0.1% TFA). The desired peaks were combined and made basic with saturated aqueous sodium bicarbonate. The CH3CN was removed and the aqueous was extracted with EtOAc. The combined organic layers were dried, filtered, and concentrated in vacuo to provide 116 mg (44%) of the title compound as a white solid. MS m/z 536.10 (MH+).
