Reaction Steps

To a solution of 2-benzyloxy-5-fluoro-pyrimidin-4-yl-cyanamide (2.9 g, 0.012 mol) in n-butanol (30 mL) in a 100 mL sealed tube was added hydroxylamine hydrochloride (4.1 g, 0.059 mol) and the solution was heated at 110° C. for 2 h. The reaction was cooled and checked by TLC and was determined to be complete. The solvent was removed in vacuo and the resulting mixture was diluted with water and extracted with EtOAc (3×30 mL). The organic layers were dried over Na2SO4, filtered, and evaporated. The crude product was purified further with reverse phase chromatography to yield the title compound (500 mg, 15% yield) as an off white solid; mp 150-152 dec.; 1H NMR (300 MHz, DMSO-d6) δ 8.72 (s, 2H), 8.44 (d, J=2.6 Hz, 1H), 7.41 (m, J=13.8, 6.3 Hz, 5H), 5.34 (s, 2H); MS (EI) m/z 278 (M)+.
