Procedure
2-(4-(4-(7-(1-Methyl-1H-pyrazol-4-yl)imidazo[1,2-c]pyrimidin-5-yl)-1H-pyrazol-1-yl)piperidin-4-yl)acetonitrile hydrochloride (Example 28, Step A; 0.050 g, 0.11 mmol) was dissolved in DIEA (0.12 mL, 0.70 mmol) and DMF (0.2 mL) with sonication. 2,2,2-Trifluoroethyl trifluoromethanesulfonate (0.025 g, 0.11 mmol) was added and the reaction was stirred at ambient temperature. After four hours the reaction was applied to a silica caplet and pumped to dryness. The caplet was applied to a silica column and eluted with 0.5-2% MeOH/DCM. The purified product was isolated to provide 2-(4-(4-(7-(1-methyl-1H-pyrazol-4-yl)imidazo[1,2-c]pyrimidin-5-yl)-1H-pyrazol-1-yl)-1-(2,2,2-trifluoroethyl)piperidin-4-yl)acetonitrile (5.0 mg, 10% yield) as a solid. MS (apci) m/z=470.2 (M+H).
