Abstract

Recently we described the solvent-free interaction of 5-aryl-3-(2-pyridyl)-1,2,4-triazine-5-carbonitriles and 2-amino-4-aryloxazoles to form 4,5-diaryl-3-hydroxy-2,2'-bipyridine-6-carbonitriles. It turned out that under absolute (anhydrous) conditions this reaction resulted in the formation of two products, namely, the previously described 4,5-diaryl-3-hydroxy-2,2'-bipyridine-6-carbonitriles (yields up to 44%) and 4,5-diaryl-2,2'-bipyridine-6-carbonitriles (yields up to 32%).
