Procedure

To a solution of 1-(4-fluorophenyl)-1H-pyrazolo[3,4-c]pyridine-4-carboxylic acid [(S)-1-(2-methylsulfanyl-oxazol-5-yl)-propyl]-amide (0.1 g, 0.2 mmol) in a mixture of acetonitrile (25 mL) and water (5 mL) was added sodium periodate (0.155 g, 0.725 mmol) followed by ruthenium trichloride (5 mg, 0.02 mmol). After 6 hours, the mixture was filtered and the filtrate was diluted with water (50 mL) and extracted with ethyl acetate (3×50 mL). The combined organic layers were dried over sodium sulfate, filtered, and concentrated. The crude material was dissolved in ethyl acetate and passed through a pad of silica. The material from the pad was crystallized from ethyl acetate-hexanes to afford the title compound.
