Procedure

To a solution of {1-[trans-4-(aminomethyl)cyclohexyl]-1H-imidazo[4,5-d]thieno[3,2-b]pyridin-2-yl}acetonitrile (9.5 mg, 0.029 mmol) and triethylamine (20 μL, 0.14 mmol) in methylene chloride (1 mL) was added methyl chloroformate (2.7 μL, 0.035 mmol). The mixture was stirred at room temperature for 1 h, then stripped to dryness and purified on prep-HPLC (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 (1.4 mg, 12%). LCMS calculated for C19H22N5O2S (M+H)+: m/z=384.1. Found: 384.0.

Workup

  1. custompurified on prep-HPLC (XBridge C18 column
  2. washeluting with a gradient of acetonitrile/water containing 0.1% ammonium hydroxide, at flow rate of 60 mL/min)
