Procedure
To a stirred solution of [6-(cyclopentylmethyl-ethyl-amino)-1,3-dimethyl-1H-pyrazolo[3,4-b]pyridine-5-ylmethyl-(3,5-bis-trifluoromethyl-benzyl)-cyanamide (0.50 g, 0.880 mmol) in ethanol (15 mL) were added H2O2 (1.5 mL) and a saturated aqueous solution of KOH (0.70 g, 11.97 mmol) at 0° C. This mixture was slowly heated to reflux. After 2 h the reaction mixture was cooled to RT, water (10 mL) was added, and the product was extracted with ethyl acetate (3×40 mL). The combined organic layers were dried over sodium sulfate and evaporated to yield the crude residue. The crude was purified by column chromatography over 100-200 mesh silica gel using 10% ethyl acetate and petroleum ether to yield the title compound as a sticky oil (yield: 60%).
