摘要:This invention relates to a novel process for preparing 3-amino-2-methylbenzotrifluoride from benzotrifluoride. The process comprises nitrating benzotrifluoride to form 3-nitrobenzotrifluoride, reacting this compound with trimethyl sulphoxonium halide to form 3-nitro-2-methylbenzotrifluoride and reducing the nitro group to an amino group.
