3-Aryl-1-benzoylthiourea reacted with chloroacetye chloride to afford 1-aryl-3-benzoyl-2- thioxo-4-imidazolidinones in 70%～84% yields in the presence of alkaline. However, using dichloroacetye chloride instead of chloroacetye chloride, 1-aryl-3-benzoyl-5-chloro-4-imidazolidinones were obtained in 36%～53% yields. The structures of the products were confirmed by IR, 1H NMR and HRMS techniques.

Key words: benzoylthiourea, chloroacetye chloride, dichloroacetye chloride, 2-thioxo-4-imidazolidinone, synthesis
