Procedure

Prepared in analogy to example 1 (b) from 5-ethanesulfonyl-2-isopropoxy-benzoic acid (Example A18) and 1-(5-trifluoromethyl-thiazol-2-yl)-piperazine hydrochloride (Example 58(c)). The crude material was purified by reversed phase HPLC (acetonitrile/water) followed by trituration in ether to yield the title compound as an off-white crystalline solid (yield 21%). MS (m/e): 492.1 (M+H+, 100%).
