Abstract
The present invention provides a simple, cost effective and time saving one step method for synthesizing triarylamines comprising two alkyl alcohol without the need for the protection and the deprotection steps. More particularly, the invention provides an improved method of producing triarylamine compounds having two alkyl alcohol groups by reaction of a primary arylamine (aniline) with a halogenated aryl alkyl alcohol. The reaction proceeds in one step, whereby a primary arylamine is reacted with two equivalents of a halogenated aryl alkyl alcohol in the presence of a catalytic amount of palladium, ligand, solvent and base.
