Synthesis Analysis
The synthesis of diaryl ureas like 1,3-Bis(4-chlorophenyl)urea can be achieved through the condensation of an amine with an isocyanate, or the coupling of amines with phosgene or a phosgene equivalent . A safer substitute for phosgene is Bis(trichloromethyl) carbonate (BTC) or triphosgene . A method for the construction of symmetrical diaryl ureas by triphosgene in the presence of triethylamine has been explored.
