Paragraph 0007, (2016/11/28)
The invention relates to a synthetic method of 2-bromo-4-(2-chloro-ethyl)-aniline and belongs to the field of chemical synthesis. The method comprises the following steps: using chlorobenzene and anhydrous AlCl2 as raw materials, dropwise adding chloroacetyl chloride, using ice water and hydrochloric acid, stirring and reacting, carrying out suction filtration, washing with sodium hydroxide and deionized water, carrying out vacuum suction filtration and collecting chlorobenzene, carrying out rotary evaporation until collecting 4-chloro-benzeneacetyl chloride, heating a 4-chloro-benzeneacetyl chloride solution, hydrazine hydrate and diglycol and carrying out reflux reaction, collecting 1-chloro-4-(2-chloroethyl)benzene and drying under reduced pressure to prepare light yellow powder, carrying out a bromination reaction and dropwise adding a sodium hypochlorite solution and an ammonium sulfite solution, washing and collecting saffron yellow particles so as to prepare 2-bromo-4-(2-chloro-ethyl)-aniline.
