Reaction Steps

To a solution of tert-butyl {(3S)-1-[5-({[2-(2,6-difluorophenyl)-1,3-thiazol-4-yl]carbonyl}amino)-1-(phenylsulfonyl)-1H-pyrrolo[2,3-b]pyridin-4-yl]piperidin-3-yl}carbamate (175.3 mg, 0.2523 mmol) in MeOH (2.0 mL), aq. NaOH (1.0 M, 2.0 mL) was added, followed by THF (2.0 mL). After stirring at room temperature for 5 h, the reaction mixture was diluted with EtOAc (50 mL), washed with brine (50 mL), dried over Na2SO4 and concentrated under reduced pressure. The residue was dissolved in DCM (2.0 mL), and TFA (2.0 mL) was added. The mixture was stirred at room temperature for 30 min., and then concentrated under reduced pressure. The resulting residue was purified using RP-HPLC (XBridge™ C18 column, eluting with a gradient of MeCN/water containing 0.15% NH4OH, at flow rate of 30 mL/min.) to afford the title compound as a white solid (59.1 mg, 52%). LCMS calc. for C22H22F2N6OS (M+H)+: m/z=455.1. found 455.1.
