For the current study, the initial intermediate from cross-coupling has not been characterized. On thin layer chromatography, it has a distinctive yellow color and is UV-active; on that basis, it is tentatively assumed to be the 3-azatriene and not the dihydropyridine. Upon further heating, the yellow TLC spot disappears and is converted to a new colorless spot that leads to the pyridine product upon workup. Additional studies will clarify the status of the intermediates in this new pyridine synthesis.
