Procedure
To a stirred solution of 5-[3-fluoro-4′-(trifluoromethyl)-2′-{[2-(trimethylsilyl)ethoxy]-methoxy}-biphenyl-4-yl]pyrimidin-2-amine in 14 mL of THF were added water (1.40 mL), acetic acid (1.40 mL) and hydrochloric acid (0.43 mL, 6 N). The reaction was stirred overnight at 65° Celsius, before diluting with ethyl acetate (20 mL) and water (20 mL). The aqueous layer was extracted with ethyl acetate (3×30 mL) and the combined organic extracts dried over Na2SO4, and concentrated to dryness. The crude product was purified by FCC to provide the title compound. MS (ESI): mass calcd. for C17H11F4N3O, 349.08; m/z found, 350.1 [M+H]+. 1H NMR (500 MHz, CD3OD) δ 8.61 (s, 2H), 7.61-7.48 (m, 4H), 7.23-7.19 (dd, J=8.3, 1.8, 1H), 7.19-7.17 (d, J=1.6, 1H).
