Preparation method of 3,5-dichloro-4-fluorobromobenzene compound

The invention relates to a preparation method of 3,5-dichloro-4-fluorobromobenzene, which comprises the steps of (1) reacting 2,4-dichloro-3-fluoroaniline with sulfuric acid in the presence of water and glacial acetic acid to obtain 2,4-dichloro-3-fluoroaniline sulfate; (2) adding bromine into the product mixture obtained in the step (1), then dropwise adding hydrogen peroxide, and reacting to obtain 2,4-dichloro-3-fluoro-6-bromoaniline sulfate; and (3) adding sodium hypophosphite and a catalyst copper salt into the product mixture obtained in the step (2), then dropwise adding sodium nitrite,and reacting to obtain 3,5-dichloro-4-fluorobromobenzene. The method is simple in process, low in cost, mild in condition, high in process safety and capable of effectively reducing the use amount ofbromine.
