该中间体在本合成路线中的序号:(IV)The known piperidinoethanol derivative (I) was converted to the mesylate (II) upon treatment with methanesulfonyl chloride and triethylamine. Displacement of the mesylate group of (II) with the spiro-substituted piperidine (III) provided adduct (IV). Finally, quaternization of piperidine (IV) with iodomethane gave the corresponding ammonium salt as a mixture of cis/trans isomers that were separated by column chromatography.
