Procedure
Prepared in analogy to example 1 (b) from 5-methanesulfonyl-2-(2,2,2-trifluoro-ethoxy)-benzoic acid (Example A3) and 1-(5-ethanesulfonyl-thiazol-2-yl)-piperazine hydrochloride (Example 32(c)). The crude material was purified by chromatography (SiO2, ethyl acetate/heptane) followed by trituration in ether to yield the title compound as a white crystalline solid (yield 72%). MS (m/e): 542.2 (M+H+, 100%), 559.3 (M+NH4+, 60%).
