Procedure

A solution of trichloromethyl isocyanate (16 grams; 0.1 mol) in diethyl ether (40 ml) is added dropwise, with stirring, to a solution of N-(3,4-dichlorophenyl) hydroxylamine (17.8 grams; 0.1 mol) in diethyl ether (60 ml) at room temperature. Stirring is continued for a period of about 1 hour resulting in the formation of a precipitate. The precipitate is recovered by filtration, is washed and dried to yield 1-trichloromethyl-3-(3',4'-dichlorophenyl)-3-hydroxyurea.
