Versuchsvorschrift

Combine sodium diformylamide (28.8 g, 0.31 mol), acetonitrile (360 g), and N,N-dimethylformamide (48 g). Add (E)-1-chloro-2-(fluoromethylene)-4-(p-fluorophenyl)butane (50.6 g, 0.23 mol). Heat to reflux. After 5 hours, cool to ambient temperature. Add water (466 g) and stir for 15 minutes. After 30 minutes, the aqueous layer is removed. Evaporate the organic layer in vacuo to give the title compound. 1H NMR (CDCl3, 300 MHz) δ 2.28 (m, 2H), 2.72 (m, 2H), 4.07 (d, J=3 Hz, 2H), 6.74 (d, J=81 Hz, 1H), 6.94 (m, 2H), 7.13 (m, 2H), 8.73 (s, 2H).
