A process for the preparation of phenolic monoesters of 2-(3-diisopropylamino-1-phenylpropyl)-4-(hydroxymethyl)phenol by converting (±)6-halo-4-phenylchroman-2-one to (±)4-halo-2-(3-hydroxy-1-phenylpropyl)phenol. The two hydroxyl groups are protected and the protected compound is reacted with diisopropylamine to give (±)[3-(2-benzyloxy-5-halophenyl)-3-phenylpropyl]diisopropylamine. The halo substituent on the benzene ring is converted to corresponding benzyl alcohol and then the protection is removed to give racemic 5-HMT. Racemic 5-HMT is converted R enantiomer and then it is esterified.
一种制备2-(3-
二异丙基氨基-1-苯基丙基)-4-(羟甲基)
酚的
酚单酯的方法,通过将(±)6-卤代-4-苯基色苷-2-酮转化为(±)4-卤代-2-(3-羟基-1-苯基丙基)
酚。两个羟基团被保护,保护化合物与
二异丙基胺反应,得到(±)[3-(2-苄氧基-5-卤苯基)-3-苯基丙基]
二异丙基胺。苯环上的卤代取代基被转化为相应的
苄醇,然后去除保护作用,得到外消旋的5-H
MT。外消旋的5-H
MT转化为R对映体,然后酯化。
