Cesium carbonate (3.1 g, 9.6 mmol) was added to 4-fluoro-2,6-dimethylphenol (0.9 g, 6.4 mmol) and methyl 3-bromo-4-fluorobenzoate (1.57 g, 6.7 mmol) ) in a solution of dimethyl sulfoxide (10 mL). The reaction mixture was stirred at 80 C for 12 hr, then cooled to room temperature, then water (50mL), ethyl acetate (50mL*2). The organic phase was washed with brine (25 mL*4) and evaporated to dryness. The crude product was separated by column ( petroleum ether: ethyl acetate = 20:1) to give methyl 3-bromo-4-(4-fluoro-2,6-dimethylphenoxy) benzoate (1.4 g, yield 62%).
According to the analysis of related databases, 82702-31-6, the application of this compound in the production field has become more and more popular.
