Reaction Steps

To a mixture of (1R)-1-(1-piperidin-4-yl-1H-imidazo[4,5-d]thieno[3,2-b]pyridin-2-yl)ethanol hydrochloride (21.6 mg, 0.0637 mmol) and triethylamine (40.0 μL, 0.287 mmol) in methylene chloride (0.78 mL) was added 2,2,2-trifluoroethyl trifluoromethanesulfonate (17.8 mg, 0.0765 mmol). The resulting mixture was stirred overnight at room temperature. The solvents were evaporated, and the crude residue purified on RP-HPLC (XBridge C18 column, eluting with a gradient of acetonitrile/water containing 0.1% ammonium hydroxide, at flow rate of 30 mL/min) to give 6.5 mg (26%) of the desired product. LCMS calculated for C17H20F3N4OS (M+H)+: m/z=385.1. Found: 385.0.
