Abstract
A method for the synthesis of 2-methyl-1-[(5-methylfuran-2-yl)methyl]-1H-benzimidazoles based on the intramolecular cyclization of vicinal N-[(5-methylfuran-2-yl)methyl]aminoanilides has been developed. A study was carried out on the protolytic opening of the furan ring leading to the formation of a diketone fragment, which was then used for the formation of N-substituted pyrrole ring by the Paal–Knorr method. The effect of the nature of the amine on the cyclization was demonstrated.
