Procedure

To a solution of ethyl 2-(4-((2-(3-chlorophenyl)-6-ethylpyrimidin-4-yl)amino)phenyl)-3,3,3-trifluoropropanoate (0.130 g, 0.28 mmol) in dioxane (11 mL) and water (7 mL) was added LiOH.H2O (0.035 g, 0.84 mmol) and the mixture was stirred at rt for 12 h. After this time, the mixture was diluted with water and extracted with ethyl acetate. The combined organic layer was dried over anhydrous sodium sulfate, filtered, and the filtrate was concentrated. The residue was purified by column chromatography (silica, hexanes/ethyl acetate) to afford the title compound (0.053 g, 53%) as a white solid. MW=395.88. 1H NMR (DMSO-d6, 500 MHz) δ 9.60 (s, 1H), 8.34-8.27 (m, 2H), 7.67 (d, J=8.5 Hz, 2H), 7.59-7.52 (m, 2H), 7.27 (d, J=8.5 Hz, 2H), 6.60 (s, 1H), 4.09 (q, J=7.1 Hz, 2H), 3.64 (s, 2H), 2.67 (q, J=7.6 Hz, 2H), 1.26 (t, J=7.6 Hz, 3H), 1.20 (t, J=7.1 Hz, 3H); APCI MS m/z 396 [M+H]+.
