Reaction Steps

To 1.6 mmol rac-5-methylsulfamoyl-2-(2,2,2-trifluoro-1-methyl-ethoxy)-benzoic acid methyl ester in 10 ml THF was added 20 mmol 2 M aq NaOH and the mixture was heated at 50° C. for 2 h. The mixture was then cooled to RT and extracted twice with ether. The aqueous phase was acidified with 10% aq citric acid and extracted twice with ethyl acetate. The combined organic phases were dried with Na2SO4. Evaporation in vacuo followed by trituration in ether and hexane afforded the title compound MS (m/e): 326.2 ([M−H]−, 100%)
