We have synthesized 4,4'-dinitro-3 4''-dimethyl triphenylamine,(1), in 84% yield in an one-step condensation process between 3,4-dimethyl aniline and 4-fluoro-nitrobenzene. After the auto-oxidation of (1) and the subsequent hydrogenation of the nitro-groups, an AB2 type triphenylamine polyimide intermediate bearing two amine groups and one acid-anhydride group each on individual phenyl ring,{AB2 PI Intermediate}, was prepared successfully. The yields of the autoxidation and the hydrogenation steps are 81% and 90% respectively.
