Procedimiento

To a solution of 3-{2-[(2-{[3-(2-bromoethyl)phenyl]amino}-5-chloropyrimidin-4-yl)amino]ethyl}phenol (50.0 mg, 0.112 mmol) in tetrahydrofuran (1.09 mL) was added a solution of sodium hydroxide in water (0.893 mL, 0.50 M). The resultant solution was stirred at rt for 2 days until the reaction was complete. The reaction was neutralized with HCl (3 M, aqueous solution) to pH 7. The aqueous layer was extracted with EtOAc twice. The combined organic layers were dried over Na2SO4, filtered, and concentrated to give the crude, which was purified by silica gel column chromatography to give the desired product as a white powder (8.5 mg, 21%). LCMS for C20H20ClN4O (M+H)+: m/z=367.0. 1H NMR (400 MHz, CD3OD): δ 7.81 (s, 1H), 7.70 (s, 1H), 7.57 (m, 1H), 7.22 (t, J=8.0 Hz, 1H), 7.08 (m, 2H), 6.69 (s, 1H), 6.67 (m, 2H), 5.73 (dd, J=6.8, 0.8 Hz, 2H), 5.14 (dd, J=7.2, 1.2 Hz, 2H), 3.72 (t, J=7.6 Hz, 2H), 2.86 (t, J=7.6 Hz, 2H).
