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.
本发明涉及一种制备替贝那嗪(TBZ)和双氢替贝那嗪(DTBZ)的方法,更具体地说,涉及使用6,7-二甲氧基-1,2,3,4-四氢异喹啉和4-甲基-2-(3-(三甲基硅基)丙-1-烯-2-基)戊烷作为起始原料,通过简单和短的反应过程依次进行烷基化反应、阿扎-普林斯环化反应,在氧化剂存在下进行氧化反应以制备替贝那嗪(TBZ)和双氢替贝那嗪(DTBZ)的方法。
