Procedure

To a solution of (1R)-1-{1-[trans-4-(aminomethyl)cyclohexyl]-1H-imidazo[4,5-d]thieno[3,2-b]pyridin-2-yl}ethanol bis(trifluoroacetate) (18 mg, 0.032 mmol) and triethylamine (22 μL, 0.16 mmol) in methylene chloride (1 mL) was added 1.0 M isopropyl chloroformate in toluene (39 μL). 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 (0.9 mg, 7%). LCMS calculated for C21H29N4O3S (M+H)+: m/z=417.2. Found: 417.1.

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)
