Procedure

Methyl 2-methoxyacetyl-3-(2-methoxyphenylamino)acrylate (55 g, 0.2 mol) was added in portions to boiling diphenyl ether (500 ml) and the mixture was heated under reflux for 45 minutes. The mixture was allowed to cool and diluted with petroleum ether to afford 3-methoxyacetyl-8-methoxy-4(1H)-quinolone (40 g, 82.5%) as light brown crystals.
