Reaction Steps

A mixture of 21.7 mmol 2-hydroxy-5-methanesulfonyl-benzoic acid methyl ester (WO 2002074774), 32.5 mmol rac-trifluoro-methanesulfonic acid 2,2,2-trifluoro-1-methyl-ethyl ester [212556-43-9] and 43.4 mmol potassium carbonate in 87 ml DMF was stirred at 80° C. for 48 hours. After cooling to room temperature, the mixture was concentrated in vacuo, resuspended in water and stirred for 1 hour. Filtration yielded the title compound.
