The Diels-Alder reaction of 5,5 -bi-1,2,4-triazines with cyclic enamines in the absence of a solvent leads to a range of symmetrical, annulated 2,2 -bipyridines in good yield. When the reaction is carried out in boiling dioxane only 5-(heteroaryl)1,2,4-triazines are formed. The latter, bearing methy
