Reaction Steps

To a solution of 4-fluoroaniline (0.2 g) in dichlbromethane (10 ml) were added in turn pyridine (0.19 ml) and diphenylcarbamoyl chloride (0.417 g) at 0° C. The mixture was allowed to warm to ambient temperature and stirred for 10 hours, and to the mixture was added N,N-dimethylaminopyridine (0.22 g), and the mixture was allowed to stir for another 1 hour. The reaction mixture was taken up into a mixture of water and ethyl acetate. The separated organic layer was washed in turn with hydrochloric acid (1N), aqueous sodium hydrogen carbonate and brine, and dried over magnesium sulfate. Evaporation under reduced pressure gave a residue, which was triturated with diisopropyl ether to give N,N-diphenyl-N′-4-fluorophenylurea (0.384 g).
