Reaction Steps

To a solution of 5-fluoro-2-(4-fluorobenzyloxy)pyrimidin-4-ylamine (0.05 g, 0.2 mmol) and a 1.0 M solution of KOtBu in tBuOH (1.0 mL, 1.0 mmol) was added nitrobenzene-sulfenyl chloride (0.044 g, 0.23 mmol) in one portion, and the resulting brown solution was stirred for 60 min. The reaction was diluted with water (2 mL) and neutralized to pH 7 with 1N HCl. The aq. phase was extracted with EtOAc (5 mL), and the organics were combined, dried over Na2SO4, filtered, and concentrated. The crude material was purified by reverse phase chromatography to yield the title compound (0.020 g, 26%) as a yellow solid: mp 184° C.; 1H NMR (300 MHz, CDCl3) δ 8.36 (d, J=7.25 Hz, 1H), 8.09 (d, J=2.3 Hz, 1H), 7.59 (m, 1H), 7.36 (m, 2H), 7.29 (m, 2H), 6.88 (m, 2H), 6.23 (bs, 1H), 5.19 (s, 2H); HPLC-MS (ESI) m/z 391 (M+H)+, 389 (M−H)−.
