Reaction Steps

To a solution of 2-(5-chloro-1H-pyrrolo[2,3-b]pyridin-3-yl)-5-fluoro-N-(piperidin-3-yl)pyrimidin-4-amine, 5c, (0.40 g, 1.15 mmol) in 10:1 mixture of CH2Cl2/DMF (8 mL) was added iPr2NEt (0.60 mL, 3.46 mmol) followed by 1-propanesulfonyl chloride (0.13 mL, 1.15 mmol). The reaction mixture was stirred at room temperature for 5 hours. The resulting residue was purified by preparatory HPLC (0.1% TFA-H2O/acetonitrile) to afford the desired product, 316.
