Abstract: Arylamine derivatives that can be utilized as hole transport or hole injection materials of organic electroluminescence devices, electrophotographic reactors, etc., and synthetic intermediates thereof, and processes of producing those. The arylamine derivative is represented by the general formula (1): wherein R1 to R4 each independently represents a hydrogen atom, an alkyl group, an alkoxy group, an aryl group, an aryloxy group, a halogen atom, an amino group, etc.; Ar1 and Ar2 each independently represents a substituted or unsubstituted aryl group or hetero-aromatic group, and Ar1 and Ar2 may form a nitrogen-containing heterocyclic ring together with the nitrogen atom to which Ar1 and Ar2 bond; and Ar3 represents a substituted or unsubstituted arylene group.
