Procedure

To a solution of 1-(4-fluorophenyl)-2-[2-(methylsulfanyl)pyrimidin-4-yl]ethanone (91.49 g,48 mmol) in acetonitrile (1.8 L) was added hydroxylamine hydrochloride (121 g, 91.7 mol) and sodium acetate (139 g, 1.7 mol). The reaction was stirred for 24 hours before 100 mL of water was added. The reaction was stirred for 24 hours. The mixture was filtered through a glass frit and the filtrate partitioned between dichloromethane and water. The layers were separated and the aqueous phase extracted with dichloromethane (2×500 mL). The organic layers were combined, washed with saturated aqueous sodium bicarbonate (300 mL), washed with brine (300 mL), dried over magnesium sulfate, filtered and concentrated. The residue was recrystalized from dichloromethane and hexanes to yield 66.4 g (69%) of 1-(4-fluorophenyl)-2-[2-(methylsulfanyl)pyrimidin-4-yl]ethanone oxime. 1H NMR (CDCl3): δ 8.75 (m, 1H), 8.42 (d, 1H), 7.75 (dd, 2H), 7.09 (t, 2H), 6.98 (d, 1H), 4.29 (s, 2H), 2.54 (s, 3H). MS m/z 278 (M+1).
