Procedure

A mixture of 4.42 g (18.47 mmol) of α-benzoylacetanilide, 1.89 g (25.84 mmol) of n-butylamine, one drop of acetic acid and 25 ml of toluene was refluxed for 1.5 hours, while the resulted water and excess of butylamine were removed through a Dean-Stark's water separator, together with about 12 ml of toluene. While heating, to the mixture was dropwise added a solution of 7.2 g (46.18 mmol) of 2-ethyl-2,6-dimethyl-4H-1,3-dioxin-4-one in 16 ml of toluene within about 30 minutes and after the resulted mixture was refluxed for forty minutes, it was cooled to room temperature. The crystals precipitated was separated by filtration and dried under vacuo to afford 3.72 g of the title compound having mp. 189.5°-193° C.
