Reaction Steps

A mixture of 1-(4-fluorophenyl)-1H-pyrazolo[3,4-c]pyridine-4-carboxylic acid [(S)-1-(2-bromopyridin-4-yl)-propyl]amide (165 mg, 0.363 mmol) and 10% palladium on carbon (77 mg) in ethanol (10 mL) was placed under 1 atmosphere of hydrogen (balloon). After 16 hours, diatamacous earth (300 mg) was added and the mixture and the solution was filtered through diatamacous earth and concentrated to afford an oil. The crude material was dissolved in a 4:1 mixture of acetonitrile in water and purified by reversed-phase HPLC. The desired fractions from the column were concentrated to remove the acetonitrile, diluted with saturated aqueous sodium bicarbonate and extracted with dichloromethane. The organic phase was dried over sodium sulfate and concentrated to afford the title compound.
