Abstract
The amination of pyridine, quinoline, and 2,3′- and 4,4′-dipyridyl N-oxides with ammonia and ammonium salts in the presence of p-toluenesulfonyl chloride was studied. 2-Aminopyridine, N-(p-tosyl)-2-aminopyridine, and N-(p-tosyl)-2,2′-dipyridyls were obtained in reactions with pyridine N-oxide. 2-Aminoquinoline was obtained in the amination of quinoline N-oxide. Dipyridyl N-oxides do not undergo amination.
