该中间体在本合成路线中的序号：(XII)Displacement of 3,5-difluorobromobenzene (VII) with the sodium alkoxide of benzyl alcohol yields the benzyl ether (VIII). Metalation of (VIII) with butyllithium, followed by addition to tetrahydropyran-4-one (IX) furnishes the carbinol adduct (X). This is converted to the methyl ether (XI) by alkylation with iodomethane in the presence of NaH. Then, hydrogenolysis of the O-benzyl group of (XI) over Pd(OH)2 provides phenol (XII). Finally, condensation between phenol (XII) and mesylate (VI) gives rise to the title compound
