N-(Hydroxymethyl)ibogaine

The title compound (systematic name: 16-hydroxy­methyl-12-methoxy­ibogamine), C21H28N2O2, was prepared by reaction of ibogaine with a formaldehyde–acetic acid solution (pH = 4). The crystal structure of this new product, belonging to the iboga indole family, is stabilized by an inter­molecular O—H⋯N hydrogen bond. The identity of the compound was confirmed by one- and two-dimensional NMR spectroscopic techniques.
