| Product | (2-Isopropoxy-5-methanesulfonyl-phenyl)-[4-(4-methyl-5-trifluoromethyl-thiazol-2-yl)-piperazin-1-yl]-methanone | HCID 11526054 | 52% |
Reaction Steps
Prepared in analogy to example 1 (b) from 2-isopropoxy-5-methanesulfonyl-benzoic acid (Example A1) and 1-(4-methyl-5-trifluoromethyl-thiazol-2-yl)-piperazine hydrochloride. The crude material was purified by chromatography (SiO2, ethyl acetate/heptane) to yield the title compound as a white foam (yield 52%). MS (m/e): 492.0 (M+H+, 100%).
