2,2,2-Trifluoroethanethiol → HCID 58372815, compound

Participants

Reaction Steps

As described for Example 21, [3-(2-bromomethyl-4-nitro-phenoxy)-4-chloro-phenyl]-acetic acid ethyl ester and 2,2,2-trifluoroethanethiol were reacted to provide {4-chloro-3-[4-nitro-2-(2,2,2-trifluoro-ethylsulfanylmethyl)-phenoxy]-phenyl}-acetic acid ethyl ester, which was reduced to the amine and then treated with pivaloyl chloride to provide {4-chloro-3-[4-(2,2-dimethyl-propionylamino)-2-(2,2,2-trifluoro-ethylsulfanylmethyl)-phenoxy]-phenyl}-acetic acid ethyl ester. Hydrolysis of the ester provided the acid.
