Reaction Steps

Aniline (0.217 mol) and diethyl oxalacetate (0.217 mol) are mixed in toluene (500 ml) and heated to reflux, i.e., about 100° C., under a water separator for approximately one hour. The toluene is then removed under vacuum to afford the desired product, i.e., diethyl 3-phenylaminobut-2-ene-dioate.
