실험 절차

To a solution of (E)- and/or (Z)-benzaldehyde-oxime (5.27 g, 44 mmol) in DMF (44 mL) was added N-chlorosuccinimide (5.81 g, 44 mmol) portionwise over 1 h, keeping the temperature below 35° C. The reaction mixture was stirred at room temperature overnight. 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 sulphate and evaporated to afford the title compound (5.91 g, 87%) which was obtained as a light yellow solid. MS m/e (EI): 155.0 [M].
