Abstract

1-Methyl-2-(5-methyl-2-furyl)-1H- and 1-methyl-2-(5-methyl-2-thienyl)-1H-benzimidazoles were synthesized by Weidenhagen reaction followed by N-methylation. The obtained 1H-benzimidazoles were formylated with hexamethylenetetramine in polyphosphoric acid and acylated with carboxylic acids in polyphosphoric acid.
