Quinone Imine Route to Benzimidazol-2-ylcarbamates. Part 2. Synthesis of 5-Sulphamido Derivatives
The synthesis of methyl 5-sulphamidobenzimidazol-2-ylcarbamates by two different routes is described.In the first, the heterocyclic ring is constructed by the classical procedure from a diamine.The second route makes use of the newly discovered oxidative
