Preparation of 3-Bromobenzoic acid: It can be obtained by m-bromotoluene through the oxidation of potassium permanganate. Mixing the m-bromotoluene, potassium hydroxide and water and heating to boiling. Adding potassium permanganate slowly, then refluxing 4h. After filtrate and acidification, filtering to get the crude. Using ammonia to disolve the crude in ethanol, and then using hydrochloric acid to acidize. Finally, after filtration and washing, we can get the product.
Uses of 3-Bromobenzoic acid: It can react with methanol to get 3-bromo-benzoic acid methyl ester. This reaction needs reagent HCl.
