该中间体在本合成路线中的序号：(I)Treatment of cinnarizine (I) with phosphate (IV) in acetonitrile in the presence of the proton scavenger 1,2,2,6,6-pentamethylpiperidine affords cinarizinium chloride (II), which is finally treated with TFA in benzene to yield the target trifluoroacetate derivative. Phosphate (IV) can be obtained from phosphite (III) by first treatment with KHCO3 and KMnO4 followed by conversion to tetramethylammonium di-tert-butylphosphate by means of tetramethylammonium hydroxide and final treatment with chloroiodomethane (A) in refluxing dimethoxyethane.
