Prepared in analogy to example 1 (b) from 2-cyclopentyloxy-5-methylsulfamoyl-benzoic acid (Example A29) and 1-(5-trifluoromethyl-[1,3,4]thiadiazol-2-yl)-piperazine trifluoroacetate (Example 62(b)). The crude material was purified by chromatography (SiO2, ethyl acetate/heptane) to yield the title compound as a white solid (yield 46%). MS (m/e): 520.3 (M+H+, 100%).
