Procedure

To a solution of 1-(4-fluorophenyl)-1H-pyrazolo[3,4-c]pyridine-4-carboxylic acid (1-piperidin-3-yl-propyl)-amide (0.10 g, 0.26 mmol) in acetonitrile (1 mL) was added Et3N (79 μL, 0.79 mmol) followed by 85% trimethylsilyl isocyanate (125 μL, 0.784 mmol). After 4 hours, the cloudy mixture was filtered and attempts to crystallize the solid proved unsuccessful. The solid and filtrate was combined and diluted with water and extracted with EtOAc. The combined organic layers were dried, filtered, and concentrated. The residue was purified by silica gel chromatography eluting with a gradient of 0-10% methanol in dichloromethane to afford the title compound as a white solid.
