(2-Chloro-acetyl)-carbamic acid ethyl ester (356 mg, 2.15 mmol) was added to 4-bromo-3-methyl-phenylamine (400 mg, 2.15 mmol) and dimethylphenylamine (273 μL, 2.15 mmol) at room temperature. The mixture was stirred at 130° C. for five hours, and the reaction solution was then cooled. The precipitate was collected by filtration and washed with CH3CN to give 1-(4-bromo-3-methyl-phenyl)-imidazolidine-2,4-dione as a colorless solid (314 mg, 54%).
