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.
本发明涉及一种从三氟甲苯制备 3-氨基-2-甲基三氟甲苯的新工艺。该工艺包括将三氟甲苯硝化形成 3-硝基三氟甲苯,将该化合物与三甲基卤化磺鎓反应形成 3-硝基-2-甲基三氟甲苯,并将硝基还原为氨基。
