Procedure

Prepared in analogy to example 1 (b) from 2-isopropoxy-5-methanesulfonyl-benzoic acid (Example A1) and 1-(4,5-dimethyl-thiazol-2-yl)-piperazine. The crude material was purified by chromatography (SiO2, ethyl acetate/heptane) followed by trituration in ether to yield the title compound as an off-white crystalline solid (yield 65%). MS (m/e): 584.3 (M+H+, 100%), 601.4 (M+NH4+, 60%).
