    摘要: The present invention relates to a method for preparing tetrabenazine (TBZ) and dihydrotetrabenazine (DTBZ), and more specifically to a method for preparing tetrabenazine (TBZ) and dihydrotetrabenazine (DTBZ) by using simple and short reaction processes of using 6,7-dimethoxy-1,2,3,4-tetrahydroisoquinoline and 4-methyl-2-(3-(trimethylsilyl)prop-1-ene-2-yl)pentane as starting materials to sequentially perform an alkylation reaction, an Aza-Prins cyclization reaction in the presence of an oxidant and an oxidation reaction.
