The invention discloses a preparation method of 2,6-dibromoaniline. In the present invention, 2,6-difluorobenzonitrile is used as the initial raw material, and 2 is synthesized through a total of six-step reactions of ammonolysis, bromine on diazotization, re-ammonolysis, bromine on diazotization, amidation and Hoffman degradation. 6-Dibromoaniline. The 2,6-dibromoaniline obtained in this process is a brown solid with a purity of more than 98%. |
