Product 1

HCID 11570050[5-Methanesulfonyl-2-((R)-2,2,2-trifluoro-1-methyl-ethoxy)-phenyl]-[4-(5-trifluoromethyl-thiazol-2-yl)-piperazin-1-yl]-methanoneYield 57%

Procedure

Prepared in analogy to example 1 (b) from 5-methanesulfonyl-2-((R)-2,2,2-trifluoro-1-methyl-ethoxy)-benzoic acid (Example A16) and 1-(5-trifluoromethyl-thiazol-2-yl)-piperazine hydrochloride (Example 58(c)). The crude material was purified by chromatography (SiO2, ethyl acetate/heptane) followed by trituration in pentane to yield the title compound as an off-white crystalline solid (yield 57%). MS (m/e): 532.0 (M+H+, 100%).
