The preparation of 5-((4-BroMo-2,6-difluorophenyl)difluoroMethoxy)-1,2,3-trifluorobenzene is as follows:Under nitrogen, the three-fluorophenyl 0-3,4,5-2,6-difluoro-4- bromophenyl thioformate 1L 4-neck flask was added 109.0g, 220mLdichloroethane was added to dissolve burning, system is heated to 60 ° C, 30%tetrahydrofuran solution of hydrofluoric acid added to the system 190.0g,250.8g of bromine was slowly dropped to the system, after dropping heatstirring 4h. Thereto was added a saturated sodium bicarbonate solution wasquenched standing layer, the aqueous phase was extracted twice with l00mLdichloroethane, the combined organic phase was washed with water and dried offthe solvent, the crude product 125 · 3g. The crudeproduct is recrystallized from ethanol 250mL white solid 105.1g, detected by GC98.9%, to close It was 95.0%.
