合成路线1
该中间体在本合成路线中的序号：(XXII)Reaction of mesylate (XVII) with triazole sodium salt (XVIII) gave (XIX). Ozonization of olefinic double bond, followed by treatment with Me2S and K2CO3 provided ketone (XX). Then, haloform reaction with NaOBr gave acid (XXI), and reduction with LiAlH4 in cold Et2O afforded primary alcohol (XXII). Alcohol (XXII) was converted to mesylate (XXIII), and this was condensed with 4-(trifluoromethoxy)phenol (XXIV) to give ether (XXV). Deprotection of the trityl group with formic acid in EtOAc and subsequent reaction with methanesulfonyl chloride provided mesylate (XXVI), which was finally condensed with mercaptoimidazole (XXVII) to furnish the target compound.
