Methyl iodide → 4-Bromo-2-fluoro-benzoic acid methyl ester

Participants

Reaction Steps

Methyl iodide (1.49 mL, 24 mmol) was added to a suspension of 4-bromo-2-fluorobenzoic acid (4.38 g, 20 mmol) and sodium carbonate (6.36 g, 60 mmol) in dimethylformamide (50 mL), and the mixture was stirred overnight at room temperature. After completion of the reaction, ethyl acetate was added, and the mixture was washed with water and a saturated ammonium chloride aqueous solution. After drying over magnesium sulfate, concentration was carried out to obtain 4.50 g of the desired product as a colorless solid (yield 97%).
