Reaction Steps

To a solution of N′-[5-fluoro-2-(4-fluorobenzyloxy)pyrimidin-4-yl]-N,N-dimethyl-formamidine (0.10 g, 0.34 mmol) in EtOH (2 mL) was added hydroxylamine hydrochloride (0.047 g, 0.68 mmol) and the mixture was agitated on an orbital shaker for 1.5 h at 50° C. The reaction mixture was cooled and evaporated to dryness. Water was added to produce a slurry which was filtered to isolate the title compound (0.090 g, 94% yield) as a white solid: mp 169-171° C.; 1H NMR (300 MHz, CDCl3) δ 8.15 (d, J=2.2 Hz, 1H), 8.02 (bs, 2H), 7.49-7.43 (m, 2H), 7.11-7.02 (m, 3H), 5.35 (s, 2H); HPLC-MS (ESI) m/z 281 (M+H)+, 279 (M−H)−.
