A convenient and simple method for the preparation of polybrominated benzimidazole derivatives has been described. Reaction of 4,5,6,7‐tetrabromo‐1‐(3‐chloropropyl)‐1H‐benzimidazole, obtained by alkylation of 4,5,6,7‐tetrabromo‐1H‐benzimidazole (TBBi) with 1‐bromo‐3‐chloropropane in the presence of KOH, with morpholine, aniline, benzylamine, N‐methyl piperazine, and 2‐arylpyrrolidines afforded new
