The synthesis of 3‐methyl‐2‐phenylbenzimidazole‐1‐oxide (VIII) has been accomplished. Consequently, it has been possible to establish the tautomeric structure of I as 1‐hydroxy‐2‐phenylbenzimidazole (Ia). Contrary to recent observations on the parent 1‐oxybenzimidazole (IV), I shows no tendency to exist as an N ‐oxide (Ib) in aqueous solution.
