  • PROCESS FOR PREPARATION OF PHENOLIC MONOESTERS OF HYDROXYMETHYL PHENOLS
    Publication number: 20110282094
    Abstract: 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.
