実験手順
A solution of acrylonitrile (10 mL), ethanol (20 mL) and 2,5-difluorophenylhydrazine (790 mg) was heated to reflux for 2 days. The reaction was concentrated under vacuum and the product purified by flash chromatography on silica gel with methylene chloride to give 790 mg (73%) 3-(2-(2,5-difluorophenyl)hydrazinyl)propanenitrile. LCMS (ESI) m+H=198.2; 1H NMR (400 MHz, CDCl3) δ 6.99 (ddd, 1H), 6.89 (ddd, 1H), 6.38 (tt, 1H), 5.45 (s, 1H), 3.91 (s, 1H), 3.19 (td, 2H), 2.61 (t, 2H).
