Abstract: PROBLEM TO BE SOLVED: To provide a method for producing trifluoromethylaniline by a simple and economical way in an excellent yield and purity and in an industrial amount. SOLUTION: This method for producing trifluoromethylaniline advantageously is provided by nitrating benzotrichloride, reacting the obtained nitrobenzotrichloride with anhydrous hydrofluoric acid for converting its trichlomethyl group into trifluoromethyl group, and finally reducing the nitro group.
