Versuchsvorschrift
Prepared in analogy to example 1 (b) from 2-cyclopropylmethoxy-5-methanesulfonyl-benzoic acid (Example A5) and 1-(5-trifluoromethyl-[1,3,4]thiadiazol-2-yl)-piperazine trifluoroacetate (Example 62(b)). The crude material was purified by chromatography (SiO2, dichloromethane/methanol 98:2) to yield the title compound as a colorless solid. MS (m/e): 491.2 (M+H+, 100%).
