Solvent-free reaction of 3,6-diaryl-1,2,4-triazine-5-carbonitriles with 2-amino-4-aryloxazoles was studied. In this case, the formation of 3- and 4-aryl-substituted pyridines (two isomeric products) in yields up to 20 and 27%, respectively, was found. This result is different from that for the reaction of 3-(2-pyridyl)-1,2,4-triazine-5-carbonitriles with these substrates. Thus, in this case, 2-amino-4-aryloxazoles act as synthetic analogues of arylacetylenes. © 2023, Pleiades Publishing, Ltd.
