Participants

Reaction Steps

To a solution of (1S)-1-{1-[(3S,6R)-6-(hydroxymethyl)tetrahydro-2H-pyran-3-yl]-1H-imidazo[4,5-d]thieno[3,2-b]pyridin-2-yl}ethanol (48.0 mg, 0.144 mmol) in methylene chloride (2.09 mL) and pyridine (70.4 μL, 0.871 mmol) was added p-toluenesulfonyl chloride (35.0 mg, 0.184 mmol) and 4-dimethylaminopyridine (1.1 mg, 0.0092 mmol). The reaction mixture was stirred at room temperature overnight. The reaction mixture was concentrated, 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 (42 mg, 60%). LCMS calculated for C23H26N3O5S2 (M+H)+: m/z=488.1. Found: 488.1.
