Procedure
To 3,4-bis-methanesulfonyl-benzoic acid tert-butyl ester (0.366 g) in dichloromethane was added trifluoroacetic acid and the reaction mixture was stirred for 3 hours. The mixture was evaporated and trituration of the residue with diethyl ether gave the title compound (0.29 g; MS: APCI+(M+H) 279).
