Abstract 2 The2′‐bisacylazide of 3,3′‐bipyridine (1) has been synthesized from the (4,7)‐phenantholine‐5,6‐dione ( 3 ) and the thermal decomposition of this new bisacylazide has been shown to give rise to the Curtius rearrangement and subsequent cyclization to the pyrido[2,3‐ h ]‐2,6‐naph‐thridinone ring system 8 .
