A mixture of (2R)-2-hydroxypropanamide (42 mg, 0.48 mmol) and triethyloxonium tetrafluoroborate (85 mg, 0.45 mmol) in tetrahydrofuran (0.65 mL) was stirred at room temperature for 2 h. The solvent was removed, and the residue dissolved in ethanol (0.27 mL) and added to a suspension of {trans-4-[(6-aminothieno[3,2-b]pyridin-7-yl)amino]cyclohexyl}methanol (41 mg, 0.15 mmol) in ethanol (0.99 mL). The resulting mixture was stirred at 85° C. for 1 h. The solvent was removed and the residue was 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 the desired product (2.3 mg, 4.7%). LCMS calculated for C17H22N3O2S (M+H)+: m/z=332.1. Found: 332.1.
