The Ullmann coupling reaction between the 2-trifluoroacetamido-3-iodo-6-benzoylimidazo[1,2-a]pyridine and dialkyldisulfides (Me, iPr) mediated by copper bronze in pyridine, resulted in a novel and highly efficient method for the incorporation of alkylthiol groups at C-3 of this type of heterocyclic system.
