该中间体在本合成路线中的序号:(VI)The bromination of labeled acetophenone (I) with Br2 and AlCl3 gives the phenacyl bromide (II), which is reduced with NaBH4, yielding 2-bromo-1-phenylethanol (III). The condensation of (III) with N-benzyl-N-[2-(3,4-dimethoxyphenyl)ethyl]amine (IV) affords the tertiary amine (V), which is debenzylated by hydrogenolysis with H2 over Pd/C to provide the substituted ethanolamine (VI). Finally, this compound is cyclized and demethylated by treatment with 48% HBr to provide the target benzazepine.
