Conditions for the Synthesis of 4,5-Diaryl-3-hydroxy-2,2'-bipyridine-6-carbonitriles by the Reaction of 1,2,4-Triazine-5-carbonitriles with 2-Aminooxazoles

Conditions for the Synthesis of 4,5-Diaryl-3-hydroxy-2,2'-bipyridine-6-carbonitriles by the Reaction of 1,2,4-Triazine-5-carbonitriles with 2-Aminooxazoles

Various conditions for the inverse electron-demand aza-Diels–Alder reaction in the series of 5-aryl-3-(2-pyridyl)-1,2,4-triazine-5-carbonitriles and 2-amino-4-aryloxazoles to obtain 4,5-diaryl-3-hydroxy-2,2'-bipyridine-6-carbonitriles were tested. Heating in 1,2-dichlorobenzene or under solvent...

Zusammenfassung:Various conditions for the inverse electron-demand aza-Diels–Alder reaction in the series of 5-aryl-3-(2-pyridyl)-1,2,4-triazine-5-carbonitriles and 2-amino-4-aryloxazoles to obtain 4,5-diaryl-3-hydroxy-2,2'-bipyridine-6-carbonitriles were tested. Heating in 1,2-dichlorobenzene or under solvent-free conditions were found to be the most effective.
