该中间体在本合成路线中的序号：(III)Reduction of ethyl 4-piperidinecarboxylate (I) with LiAlH4 in THF provided 4-piperidinemethanol (II), which was coupled with 3-ethoxybenzoyl chloride (III) in the presence of Et3N, yielding amide (IV). Subsequent treatment of (IV) with p-toluenesulfonyl chloride in pyridine afforded the corresponding tosylate (V. This was finally condensed with 5,8-dimethoxy-1,2,3,4-tetrahydroisoquinoline (VI) to furnish the title compound.
