Participants

Reaction Steps

To a solution of (1R)-1-{1-[(3S,6R)-6-(aminomethyl)tetrahydro-2H-pyran-3-yl]-1H-imidazo[4,5-d]thieno[3,2-b]pyridin-2-yl}ethanol (11 mg, 0.033 mmol) in methanol (0.5 mL) was added N,N-diisopropylethylamine (17 μL, 0.099 mmol) and methanesulfonyl chloride (2.8 μL, 0.036 mmol). After stirring for 0.5 h, another equivalent of methanesulfonyl chloride was added. After stirring for 20 min, The reaction solution 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 30 mL/min) to give the desired product (5 mg, 37%). LCMS calculated for C17H23N4O4S2 (M+H)+: m/z=411.1. Found: 411.1.
