Procedure
Prepared in analogy to example 1 (b) from 2-(2,2-dimethyl-propoxy)-5-methanesulfonyl-benzoic acid (Example A11) and 1-(5-benzenesulfonyl-thiazol-2-yl)-piperazine hydrochloride (Example 4(d)). 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 57%). MS (m/e): 578.2 (M+H+, 100%), 595.3 (M+NH4+, 92%).
