Versuchsvorschrift

To a solution of (E)- and/or (Z)-4-fluoro-benzaldehyde oxime (100 g, 719 mmol) in DMF (500 mL) was added N-chlorosuccinimide (110 g, 791 mmol) portionwise keeping the temperature below 70° C. The reaction mixture was stirred at room temperature for 2.5 h and then extracted with tert-butyl methyl ether to afford the title compound (125 g, 100%) which was obtained as a yellow oil. MS: m/e=173.1 [M]+.
