A mixture of 4-bromo-2-(carboxymethyl)benzoic acid (1.00 g, 3.86 mmol) in acetyl chloride (13.72 ml, 193 mmol, 50.0 equiv.) was stirred at 150° C. for 15 min. in a microwave. Upon completion of the reaction, the excess solvent was concentrated and dried to yield 740 mg of 6-bromoisochroman-1,3-dione as a white solid which was used as such without any further purification.
