Versuchsvorschrift
Prepared in analogy to example 1 (b) from 5-methanesulfonyl-2-(2,2,2-trifluoro-1,1-dimethyl-ethoxy)-benzoic acid (Example A14) and 1-[5-(2,2,2-trifluoro-ethyl)-thiazol-2-yl]-piperazine hydrochloride (Example 69(e)). The crude material was purified by chromatography (SiO2, ethyl acetate/heptane) to yield the title compound as a white crystalline solid (yield 27%). MS (m/e): 560.3 (M+H+, 100%).
