Reaction Steps

A solution of trifluoromethyl isocyanate (11.1 grams; 0.1 mol) in diethyl ether (50 ml) is added dropwise, with stirring, to a solution of N-(3-methylphenyl) hydroxylamine (12.3 grams; 0.1 mol) in diethyl ether (50 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-trifluoromethyl-3-(3'-methylphenyl)-3-hydroxyurea.
