To 1.0 g (3.8 mmol) of 1-(6-bromohexyl)-2,3-dihydroxybenzene in 150 mL of ethyl acetate and 15 mL of acetic anhydride was added 0.03 mL of 70% perchloric acid. The solution was left at room temperature for 1.5 hours and then was washed with sodium bicarbonate solution. After drying, the organic layer was concentrated to give 1.3 g of 1-(6-bromohexyl)-2,3-bis(acetyloxy)benzene as an oil.
