Versuchsvorschrift

To a solution of 3-chloro-3-(2-chlorophenyl)acrylonitrile (1.2 g, 6.05 mmol, 1 eq.) in 15 ml of MeCN was added 2-ethylcyclopropanamine hydrochloride (0.633 g, 7.27 mmol, 1.2 eq.) followed by TEA (0.919 g, 7.08 mmol, 1.5 eq.). The reaction was microwaved (130° C., 2000 s, fixed hold, high absorption) and the solvent evaporated. The residual oil was triturated in ethyl acetate and the white solid removed by filtration. After concentration under vacuum, the residual oil was subjected to column chromatography to give 3-(2-chlorophenyl)-3-[(3-methylbutan-2-yl)amino]acrylonitrile (1.36 g, 89% yield).
