Abstract
The process of preparing a tertiary amine by the condensation of a mono- or di-tertiary amine and a mono- or di-iodoaryl compound. Conducting the condensation reaction in the presence of potassium hydroxide, and a copper catalyst, either in the absence of a solvent or with an inert saturated hydrocarbon solvent, in an inert atmosphere, at a temperature between from about 120.degree. C. to about 190.degree. C. for a period of time sufficient to at least substantially complete the reaction.
