実験手順
A solution of ethyl 2-(4-((2-(3-chlorophenyl)-6-ethylpyrimidin-4-yl)amino)phenyl)-3,3,3-trifluoropropanoate (0.070 g, 0.15 mmol) in dichloromethane (3 mL) at 0° C. was slowly treated with DIBAL (0.064 g, 0.45 mmol) dropwise and the resulting mixture was stirred for 2 h and then warmed to rt for 2 h. After this time, the reaction was quenched with methanol, 2M HCl, and water and then 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 (0.035 g, 51%) as a white solid. MW=421.84. 1H NMR (DMSO-d6, 300 MHz) δ 9.71 (s, 1H), 8.38-8.27 (m, 2H), 7.75 (d, J=8.4 Hz, 2H), 7.61-7.52 (m, 2H), 7.39 (d, J=8.4 Hz, 2H), 6.63 (s, 1H), 5.10 (t, J=5.4 Hz, 1H), 4.02-3.91 (m, 1H), 3.90-3.80 (m, 1H), 3.77-3.61 (m, 1H), 2.69 (q, J=7.6 Hz, 2H), 1.27 (t, J=7.6 Hz, 3H); APCI MS m/z 422 [M+H]+.
