The solution was warmed to reflux of dioxane for 5 days. After cooling, dichloromethane was added and the solution was washed by water and sodium hydroxide 1N. The organic layer was separated and dried over sodium sulfate. The solvent was removed and the mixture was purified by chromatography on silica gel (dichloromethane/ethanol (95:5)) to afford N-phenyl-N-quinolin-4-yl-acetamide (10 g).
