3-(2,2-dimethyl-4-oxo-4H-1,3-dioxin-6-yl)-2 oxopropyl acetate (4.00 g, 16.52 mmol) was dissolved in 1,4-dioxane (160 mL) and 3-aminobenzamide (1.73 g, 12.71 mmol) was added. The reaction was heated to reflux for 1 hour then cooled to 70° C. Methanesulfonic acid (1.22 g, 12.71 mmol) was added and the reaction brought back to reflux for 1 hour. The reaction was cooled to room temperature, concentrated and used as crude product for the next step.
