合成路线1
该中间体在本合成路线中的序号:(III)The reduction of 4-(p-methoxyphenyl)-3-buten-2-one (II) with hydrogen over Raney-Ni in ethyl acetate gives the corresponding butanone (III), which is then condensed with homoveratrylamine (IV) in the same solvent to give the imine (V). This product, without isolation, is reduced again with hydrogen over Pd/C to yield 3,4-dimethoxy-N-[3-(4-hydroxyphenyl)-1-methylpropyl]-beta-phenylethylamine (I), which by demethylation with HBr in refluxing acetic acid.
