Versuchsvorschrift

Aniline (0.20 mol) and ethylacetoacetate (0.20 mol) are mixed in toluene (200 mL) containing 0.04 g of p-toluenesulfonic acid-hydrate and heated at reflux under a water separator for one hour. The toluene is removed under vacuum to afford the ethyl-3-phenylaminobut-2-enoate which can be used as is for the preparation of the ethyl 2-methyl-3-quinolinecarboxylate.
