Procedure

To a solution of tert-butyl N-[2-(4-[[4-(morpholin-4-yl)cyclohexyl]oxy]thieno[2,3-d]pyrimidin-6-yl)ethyl]carbamate (150 mg, 0.32 mmol, 1.00 equiv) in DCM/H2O (10/0.5 mL) was added trifluoroacetic acid (0.8 mL) at 0° C. and stirred overnight at room temperature. After concentration under vacuum, the residue was dissolved in DCE (30 mL) and paraformaldehyde (180 mg) and trifluoroacetic acid (1 mL) were added. The resulting solution was stirred overnight at 45° C. under nitrogen. After concentration under vacuum, the residue was purified by preparative HPLC under the following conditions: Column: XBridge Shield RP18 OBD, 5 μm, 19*150 mm; mobile phase: water (with 0.5% TFA) and CH3CN (0% CH3CN up to 21% in 12 min, up to 95% in 2 min, down to 0% in 2 min); flow rate: 20 mL/min; UV detection at 254/220 nm. After concentration under vacuum, the desired 3-[[4-(morpholin-4-yl)cyclohexyl]oxy]-8-thia-4,6,12-triazatricyclo[7.4.0.0[2,7]]trideca-1(9),2(7),3,5-tetraene trifluoroacetate (100 mg, crude) was obtained as a light yellow solid. MS (ES): m/z 375 (M+H)+.
