Synthesis

Literature [Synthetic Communications 2010, 40, 732] in accordance with the general method described, 4-bromoaniline (30.0 g, 174 mmol) and 2,2-dimethyl-l, 3-dioxane-4,6-dione ( 25.1 g, was heated in 174 mmol) in 80 for 1.5 hours, cooled to ambient temperature, 3 - ((4-bromophenyl) amino) -3-oxo-propane to give the acid.By removing the acetone by-product under vacuum to give the intermediate product as a dry solid.It was added to Eaton's Reagent (100 mL) to the solid, the mixture obtained in and then heated to 70 overnight, cooled to room temperature.The mixture was poured into water, the brown precipitate was filtered, and rinsed with water.With ethanol, the brown precipitate tree illustration in the tube, and then filtered to give the title compound as a light brown solid.
