HCID 21100183, compound → {4-[5-(Butane-1-sulfonyl)-thiazol-2-yl]-piperazin-1-yl}-[5-methanesulfonyl-2-(2,2,2-trifluoro-ethoxy)-phenyl]-methanone

Participants

Reaction Steps

Prepared in analogy to example 1 (b) from 5-methanesulfonyl-2-(2,2,2-trifluoro-ethoxy)-benzoic acid (Example A3) and 1-[5-(butane-1-sulfonyl)-thiazol-2-yl]-piperazine hydrochloride (Example 38(c)). 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 63%). MS (m/e): 570.4 (M+H+, 15%), 587.3 (M+NH4+, 100%).
