This invention relates to a novel process for preparing 3-amino-2-methylbenzotrifluoride from 4-X-substituted-2-methylthiomethylbenzotrifluorides. The former compounds are useful in the preparation of anilino-nicotinic and anilino-anthranilic acids exhibiting analgesic, anti-inflammatory or anti-diarrheal properties. Some of the intermediates are novel per se.
