Synthesis method of 2-(2, 2-difluoroethyoxyl)-6-trifluoromethyl benzenesulfonyl chloride

The invention discloses a synthesis method of 2-(2, 2-difluoroethyoxyl)-6-trifluoromethyl benzenesulfonyl chloride. The preparation method comprises the following steps: dissolving 2-trifluoromethyl-4-nitro-bromobenzene in sulfuric acid, adding a halogenating reagent, and reacting at 50-100 DEG C for 1-8 hours; dissolving the obtained 2-bromo-3-trifluoromethyl-5-nitro-benzene halide in a solvent, and performing reduction in a reduction system; carrying out diazotization on the obtained 3-halo-4-bromo-5-trifluoromethyl-aniline, and then carrying out decomposition on the obtained 3-halo-4-bromo-5-trifluoromethyl-aniline; carrying out Grignard reaction on the obtained 2-bromo-3-trifluoromethyl-benzene halide, and then reacting with dialkyl disulfide; carrying out etherification reaction on the obtained 2-alkylthio-3-trifluorotoluene-benzene halide and 2, 2-difluoroethanol in an organic solvent under the action of an alkali; and reacting the obtained 2-(2, 2-difluoroethoxy)-6-trifluoromethyl-phenylalkyl sulfide with chlorine gas at 10-60 DEG C for 1-5 hours. The method is short in route, mild in condition, high in yield and suitable for industrial production.
