実験手順

To a solution of (E)- and/or (Z)-2-fluoro-benzaldehyde oxime (66.8 g, 480 mmol) in DMF (334 mL) was added N-chlorosuccinimide (29.4 g, 211 mmol) portionwise and after 10 min, keeping the temperature below 50° C., N-chlorosuccinimide (44.1 g, 317 mmol) was added portionwise. The reaction mixture was stirred at room temperature for 2 h and then extracted with tert-butyl methyl ether to afford the title compound (91.9 g, 91%) which was obtained as a yellow oil. 1H-NMR (CDCl3): 7.10-7.25 (m, 2H), 7.40-7.50 (m, 1H), 7.64-7.70 (m, 3H), 8.99 (s, 1H).
