실험 절차

The process of claim 18 in which 2-methyl-6-trifluoromethyl aniline is prepared by reacting 1-nitro-2-trifluromethylbenzene with carbon monoxide at elevated pressure over a noble metal catalyst to obtain 2-trifluoromethylphenyl isocyanate, such isocyanate is reacted with dimethyl sulfoxide in the presence of strong acid to produce 2-trifluoromethylphenyl-S,S-dimethylsulfilimine; the sulfilimine is rearranged in the presence of a rearrangement catalyst to 2-methylthiomethyl-6-trifluoromethylaniline and desulfurized under reductive conditions to obtain 2-methyl-6-trifluoromethylaniline.
