32.5 g (0.25 mol) of sodium-3-hydroxyacrylonitrile (content 70%) is added to a suspension of cyclohexylamine hydrochloride (composed of 29.8 g (0.3 mol) of cyclohexylamine and gaseous hydrochloric acid) in 150 ml of ethanol and the mixture is stirred for 24 h at 25° C. After removal of the solid by filtration, and withdrawal of the solvent followed by recrystallization from carbon tetrachloride, 32.1 g (85.6%) of 3-cyclohexylaminoacrylonitrile was obtained.
