Abstract
Azomethines containing benzimidazole and furan rings are synthesized from 2-aminobenzimidazoles and 5-substituted furfurals. Some of the resulting azomethines are converted to iodomethylates. The imidazole ring of 2-furfurylideneaminobenzimidazoles has a diminished reactivity to electrophilic reagents because the π-electrons of the imidazole and furan rings are conjugated across an N=CH group.
