| Product | [5-Methanesulfonyl-2-((S)-2,2,2-trifluoro-1-methyl-ethoxy)-phenyl]-[4-(5-trifluoromethyl-[1,3,4]thiadiazol-2-yl)-piperazin-1-yl]-methanone | HCID 11562813 | 52% |
Reaction Steps
Prepared in analogy to example 1 (b) from 5-methanesulfonyl-2-((S)-2,2,2-trifluoro-1-methyl-ethoxy)-benzoic acid (Example A15) and 1-(5-trifluoromethyl-[1,3,4]thiadiazol-2-yl)-piperazine trifluoroacetate (Example 62(b)). The crude material was purified by chromatography (SiO2, ethyl acetate/heptane) to yield the title compound as an off-white solid (yield 52%). MS (m/e): 533.0 (M+H+, 100%).
