Procedure
To a room temperature solution of 1-(4-fluorophenyl)-1H-pyrazolo[3,4-c]pyridine-4-carboxylic acid [(S)-3-azido-1-(2-methanesulfonyl-pyridin-4-yl)-propyl]amide (86 mg, 0.17 mmol) in THF (7 mL) was added triphenylphosphine (57 mg, 0.22 mmol) (gas evolved) followed by water (700 μL). After 75 hours, the mixture was concentrated acetonitrile was added and the solution was filtered through a 0.45 um nylon Acrodisc and purified by reversed-phase HPLC using a 20 minute gradient of 5-95% MeCN (0.1% TFA) in H2O (0.1% TFA) (flow rate=25 mL/minute). The desired fractions were lyophilized to afford the title compound as a yellow solid.
