A solution of tert-butyl-4-(1,1,3,3-tetraoxidobenzo[d][1,3,2]dithiazol-2-yl)benzoate, 5, (0.77 g; 1.8 mmol) in dichloromethane (10 mL) was treated with trifluoroacetic acid (5 mL) and allowed to stir at ambient temperature for a period of 2 hours. The solvent was removed under reduced pressure to afford 4-(1,1,3,3-tetraoxidobenzo[d][1,3,2]dithiazol-2-yl)benzoic acid, 6, (0.67 g; 84%). The compound was used without further purification.
