To a solution of 3-{2-[(2-{[3-(bromomethyl)phenyl]amino}-5-chloropyrimidin-4-yl)amino]ethyl}phenol (25.0 mg, 0.0576 mmol) in tetrahydrofuran (0.561 mL) was added a solution of sodium hydroxide in water (0.46 mL, 0.50 M). The resultant solution was stirred at rt for 16 hours until the reaction was complete. The reaction mixture was neutralized with aqueous HCl solution (3 M) to pH 7. The aqueous layer was extracted with EtOAc twice. The combined organic layers were dried over Na2SO4, filtered, and concentrated (then triturated with cold EtOAc) to give the desired product as an off-white powder (13 mg, 65%). LCMS for C19H18ClN4O (M+H)+: m/z=353.0. 1H NMR (400 MHz, CD3OD): δ 7.72 (s, 1H), 7.52 (s, 1H), 7.29 (t, J=7.6 Hz, 1H), 7.19 (s, 1H), 7.10 (dd, J=7.6, 0.8 Hz, 1H), 7.06 (t, J=7.2 Hz, 1H), 6.93 (dd, J=7.2, 0.8 Hz, 1H), 6.73 (dd, J=2.4, 0.8 Hz, 1H), 6.66 (d, J=7.2 Hz, 1H), 5.25 (s, 2H), 3.70 (m, 2H), 2.72 (t, J=6.8 Hz, 1H).
