Reaction Steps

A mixture of o-anisidine (15.11 g), ethyl propionylacetate (17.69 g) and acetic acid (0.5 ml) in benzene (30 ml) was refluxed removing water for 24 hours. The solvent was removed in vacuo, and the residue was dissolved in toluene (30 ml). The reaction mixture was refluxed for an additional 8 hours. The solvent was removed in vacuo. The residue was purified by column chromatography (hexane-ethyl acetate) to give ethyl 3-(2-methoxyanilino)-2-pentenoate (15.11 g) as an oil.
