Reaction Steps

To a solution of 4-bromo-3-methylbenzoic acid (commercially available) (1.0 eq.) in EtOH (0.3 M) was added thionyl chloride (1.5 eq.) and heated to reflux for 2 hours. The solvent was concentrated en vacuo, and the residue was diluted in ether and neutralized with saturated aqueous sodium bicarbonate solution. The two phases were separated, and the aqueous layer was extracted with ether. The combined organic layers were washed with brine, dried over anhydrous MgSO4, and concentrated en vacuo to give ethyl 4-bromo-3-methylbenzoate.
