A solution of 0.47 mL (7.01 mmol) of chlorosulfonic acid in 7 mL of dichloromethane was added drop by drop to a solution of 1.6 g (7.01 mmol) of 3-methoxyphenyl benzoate in 12 mL of dichloromethane at 0° C. Once the addition was completed, the mixture was left to react for 18 h at room temperature. The formed precipitate was filtered, giving 300 mg of 4-benzoyloxy-2-methoxybenzenesulfonic acid.
