The addition of aryllithium compounds to pyridine followed by air oxidation gives satisfactory yields of several 2-arylpyridines. These are readily oxidized by perbenzoic acid to 2-arylpyridine-N-oxides, from which 2-aryl-4- and 6-chloropyridines may be obtained. 2-Arylpyridines and aryllithiums give low yields of 2,6-diarylpyridines. From three different 2-arylpyridines three antimalarials modelled after the plasmoquin type have been prepared.
