Reaction Steps

A solution of bromine (0.338 mL, 6.60 mmol) in acetic acid (6 mL) was added dropwise to a mixture of ethyl 2,5-diethoxybenzoate (1.36 mL, 6.02 mmol) and acetic acid (24 mL) cooled in a water bath. After stirring 1 h, more bromine (0.102 mL, 1.99 mmol) was added dropwise to the reaction mixture. After stirring an additional 4 h, the reaction mixture was concentrated under reduced pressure and the residue was purified by flash column chromatography (eluting with 10% diethyl ether in hexanes) to give ethyl 4-bromo-2,5-diethoxybenzoate as an off-white solid (0.610 g, 32%).
