Procedure

To a solution of {(2R,5S)-5-[(6-aminothieno[3,2-b]pyridin-7-yl)amino]tetrahydro-2H-pyran-2-yl}methanol (115 mg, 0.412 mmol) in acetic acid (1.1 mL) was added propane, 1,1,1-triethoxy- (265 μL, 1.32 mmol). The resulting mixture was stirred at 120° C. for 30 min. After cooling to room temperature, the mixture was diluted with methanol and purified with prep-LCMS (XBridge C18 column, eluting with a gradient of acetonitrile/water containing 0.1% ammonium hydroxide, at flow rate of 60 mL/min) to give the desired product as white solid (74.8 mg, 57%). LCMS calculated for C16H20N3O2S (M+H)+: m/z=318.1. Found: 318.1.
