Procedure

A mixture of (2R)-2-hydroxypropanamide (320 mg, 3.6 mmol) and triethyloxonium tetrafluoroborate (0.69 g, 3.6 mmol) in tetrahydrofuran (3 mL) was stirred at room temperature for 1 h and then concentrated. A mixture of tert-butyl {4-[(6-aminothieno[3,2-b]pyridin-7-yl)amino]cyclohexyl}carbamate (191 mg, 0.527 mmol) and the above made reagent in ethanol (4.8 mL) was heated at reflux for 2 h. The mixture was concentrated and purified on silica gel column (eluting with 0-10% MeOH in methylene chloride) to give the desired product. LCMS calculated for C21H29N4O3S (M+H)+: m/z=417.2. Found: 417.0.
