摘要：

An Ullmann reaction between 2‐bromonicotinic acid and 2,6‐diaminopyridine gave 6 ‐amino‐2,2 ‐dipyridylamino‐3‐carboxylic acid (V). The latter was converted into 7‐amino‐5H‐dipyrido‐[1,2‐a:2,3 ‐d]pyrimidin‐5‐one (VII) by heating with polyphosphoric acid and into 2‐amino‐5,10 H‐anthyridin‐5‐one (VIII) by heating with concentrated sulfuric acid. Structure proofs of VII and VIII are given and some derivatives of VIII are described. Copyright © 1969 Journal of Heterocyclic Chemistry
