Abstract
The present invention is directed to 2-acetyl-6-cyanopyridine compounds that are useful as intermediates in the synthesis of oligo-2,6-pyridines. The present invention is also directed to new, simpler, less expensive methods for synthesizing such oligopyridines using the novel 2-acetyl-6-cyanopyridine compounds as intermediates.
