In a study of the synthesis (unsuccessful) of pyrido[3,4‐ e ]‐as‐triazino‐3 (4 H )one (6) , the acidification of 2‐(3‐amino‐4‐pyridyl)hydrazinecarboxylate hydrochloride (8) unexpectedly gave 1‐amino‐1 H ‐imidazo[4,5‐ c ]pyridin‐2(3 H ) one hydrochloride (10). The isolation and characterization of 10 has been described.
