Procedure
Prepared in analogy to example 1 (b) from 2-isopropoxy-5-methanesulfonyl-benzoic acid (Example A1) and 1-(5-trifluoromethyl-[1,3,4]thiadiazol-2-yl)-piperazine trifluoroacetate. The crude material was purified by chromatography (SiO2, dichloromethane/methanol 99:1) to yield the title compound as a colorless solid. MS (m/e): 479.2 (M+H+, 100%).
