To the suspension of 2-fluoro-3-methoxybenzoic acid (20 g, 118 mmol) in Acetic Acid (100 mL) and water (100 mL) at RT, bromine (12.05 mL, 235 mmol) was added dropwise. The reaction mixture was heated for 1 h at 60° C. The reaction was then cooled to RT and white precipitate was filtered. The solid was washed with excess water and dried to give 6-bromo-2-fluoro-3-methoxybenzoic acid (24.68 g, 99 mmol) as a white solid.
