合成路线1
该中间体在本合成路线中的序号：(VI)4-Hydroxy-2-methyl-indole (IV) can be quaternized with MeI yielding the ammonium salt (VI), which by heating with aqueous NaCN in converted into 2-cyanomethyl-4-benzyloxyindole (VII). The hydrolysis of (VII) affords the corresponding acid (VIII), which is decarboxylated to 4-benzyloxy-2-methyl-indole (IX). Finally, this compound is hydrogenated to the previously obtained 4-hydroxy-2-methyl-indole (V).
