Reaction Steps
1-Bromo-3-(bromomethyl)-2,4-difluoro-benzene (45.2 g, 0.158 M) was dissolved in dioxane (800 mL), water (800 mL) and calcium carbonate (80 g, 0.80 M) were added and the mixture was refluxed for 16 h. The mixture was cooled, acidified with 2N HCl and extracted with dichloromethane. Organic phases were pooled, dried with Na2SO4 and and evaporated to yield a brownish oil (40.3 g). The residue was purified by column chromatography (silica gel; n-hexane/ethyl acetate 9:1) to yield 31.2 g (88%) of the title compound as a colorless solid. MS (EI): 224.0 (M)+.
