Procedure

A solution of methyl 5-(methanesulfonyl)salicylate [101371-44-2] (0.50 g), trifluoro-methanesulfonic acid 2,2,3,3,3-pentafluoro-propyl ester (0.67 g) and potassium carbonate (0.60 g) in acetone was stirred at 60° C. for 5 hours. The reaction mixture was then concentrated in vacuo and purified by column chromatography (SiO2) to yield the title compound as a white solid (0.44 g). MS (m/e): 363.1 (M+H+, 100%).
