Reaction Steps
A mixture of ethyl butyrylacetate (100 g, 0.63 mol), triethyl orthoformate (210 ml, 1.26 mol) and acetic anhydride (60 ml, 0.63 mol) was heated under reflux for 6 hours, then excess triethyl orthoformate evaporated in vacuo. The residue consisted mainly of ethyl 2-butyryl-3-ethoxyacrylate as a mixture of E and Z isomers, and was used without further purification.
