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

Participants

Reaction Steps

Prepared in analogy to example 1 (b) from 2-(2,2-dimethyl-propoxy)-5-methanesulfonyl-benzoic acid (Example A11) 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 69%). MS (m/e): 558.4 (M+H+, 20%), 575.4 (M+NH4+, 100%).
