Reaction Steps

Propane-1-sulfonic acid (3-{5-[6-(3-diethylamino-prop-1-ynyl)-pyridin-3-yl]-1H-pyrrolo[2,3-b]pyridine-3-carbonyl}-2,4-difluoro-phenyl)-amide (P-2222, 20.3 mg, 0.0359 mmol) was dissolved in 0.14 mL of methanol. Platinum dioxide (0.81 mg, 0.0036 mmol) was added and the resulting mixture was stirred under an atmosphere of hydrogen for 1 hour. The mixture was filtered through a bed of celite and the filtrate was concentrated. The crude material was purified by flash silica gel chromatography, eluting with a gradient of 15% methanol in dichloromethane to 1% methanol in dichloromethane. The appropriate fractions were combined and concentrated to provide the desired compound as a solid. MS (ESI) [M+H+]+=499.4.
