Procedure
To a solution of (E)- and/or (Z)-3-fluoro-benzaldehyde oxime (6.9 g, 50 mmol) in DMF (50 mL) was added N-chlorosuccinimide (6.6 g, 50 mmol) portionwise over 1 h, keeping the temperature below 35° C. The reaction mixture was stirred at room temperature for 1 h. The mixture was then poured onto ice-water, and extracted with ethyl acetate. The combined organic layers were then washed with water and brine, dried over sodium sulfate and evaporated to afford the title compound (6.3 g, 73%) which was obtained as an off white solid. MS m/e (EI): 173.1 [M].
