Procedure

4-Aminoacetophenone (1.35 g) in toluene (20 mL) was treated with trichloromethyl chloroformate (1.2 mL). The mixture was heated at reflux for 2 hr. 3,5-diacetylaniline (1.77 g) was added and the mixture was heated at reflux for 1 hr then allowed to stand 16 hr at room temp. The product was filtered off and washed with ethanol and dried to give 0.93 g of N-(4-acetylphenyl)-N′-(3,5-diacetylphenyl)urea, mp 251-2° C.
