Procedure

To a mixture of 1-[1-(3-azetidin-3-yl-5-chloro-2-ethoxy-4-fluorophenyl)ethyl]-3-methyl-1H-pyrazolo[3,4-d]pyrimidin-4-amine dihydrochloride (19 mg, 0.040 mmol, racemic intermediate from Example 139, Step 6) and triethylamine (20 μL, 0.14 mmol) in dichloromethane (0.5 mL) was added 2,2,2-trifluoroethyl trifluoromethanesulfonate (11 mg, 0.048 mmol). The resulting mixture was stirred overnight at room temperature. The solvents were evaporated under reduced pressure and the crude mixture 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 (3.8 mg, 19%). The product was isolated as a racemic mixture. LCMS calculated for C21H24ClF4N6O (M+H)+: m/z=487.2; Found: 487.1.
