thionyl chloride followed by an aniline to give the amides (4)(70%). Refluxing in toluene with sodium hydride for 12 h transfers intramolecularly the 1-aryl group of the pyridinium salt (4) to the nitrogen of the amide. Aqueous work-up cleaves (6) and the diarylamine is purified by sublimation (60%)(overall yield ca. 30%).
