Chemical Properties
White solid powder
Uses
4-Bromo-3-fluorobenzoic acid is an important chemical raw material and can be used to prepare a variety of drugs (such as the anticancer drug benzamide).
Synthesis
452-74-4
153556-42-4
The general procedure for the synthesis of 3-fluoro-4-bromobenzoic acid from 3-fluoro-4-bromotoluene was as follows: potassium permanganate (66.0 g, 0.42 mol) was added to a mixed solution of pyridine and water (1:1 ratio, 200 mL) containing 1-bromo-2-fluoro-4-methylbenzene (20.0 g, 0.10 mol) in batches. The reaction mixture was stirred at 90 °C for 3 hours. After completion of the reaction, it was cooled to room temperature and filtered through a diatomaceous earth pad. The diatomaceous earth pad was washed sequentially with 3N sodium hydroxide solution (500 mL) and water (400 mL). Subsequently, ethanol was removed by distillation under reduced pressure and the residue was acidified to pH=2 with 6N hydrochloric acid to produce a white precipitate. The precipitate was filtered and dried to give 4-bromo-3-fluorobenzoic acid as a white solid (17.0 g, 73% yield).
