Versuchsvorschrift
A mixture of ethyl 2-butyryl-3-ethoxyacrylate (23.5 g, 0.11 mol) and 2'-aminoacetophenone (13.5 g, 0.1 mol) was warmed on a steam bath for 10 minutes. Crystallisation from petroleum ether gave ethyl 2-butyryl-3-(2-acetylphenylamino)acrylate as a mixture of E/Z isomers (14.9 g, 49%).
