(1-Hydroxycyclohexyl)(4-methoxyphenyl)acetonitrile

(1-Hydroxycyclohexyl)(4-methoxyphenyl)acetonitrile is an important synthetic intermediate used during the preparation of Venlafaxine. This compound contains the cyclohexanol and 4-methoxyphenyl structural features required for the Venlafaxine framework. In the synthetic process, it undergoes further functional group transformations such as reduction and amine introduction, which lead to the formation of the final Venlafaxine active pharmaceutical ingredient. Venlafaxine synthesis involves several intermediates.
