use	2,4-dibromoanisole is a very important organic synthesis and chemical pharmaceutical intermediate, which can be widely used in laboratory research and development and pharmaceutical research and development.
preparation	after adding 2, 4-dibromofluorobenzene (20.0g,0.08mol,1eq.) and anhydrous DMF(350 mL) to a 500mL round bottom flask, slowly adding sodium methoxide (5.2g,0.09mol,1.2eq.) to the round bottom flask, and stirring vigorously overnight at room temperature, then 5% HCl was added to neutralize and the reaction was stopped. CH2Cl2 extraction (50mL × 3), organic phase washed with distilled water (50mL × 3), anhydrous magnesium sulfate drying organic phase, filtration to remove magnesium sulfate, spin evaporation to remove solvent to obtain light yellow solid, silica gel chromatography column purification (eluent: petroleum ether), to obtain 30g of white solid with a yield of 95%.
