Procedure
A mixture of ethyl 2-butyryl-3-ethoxyacrylate (95 g, 0.4 mol) and aniline (36 ml, 0.4 mol) was heated at reflux for 30 minutes, then cooled, diluted with petroleum ether, and left to crystallise at -20° overnight. Filtration and washing gave ethyl 2-butyryl-3-(phenylamino)acrylate (72 g, 60%) as a mixture of E and Z isomers.
