An efficient selective C(3)–H arylation of furan ring in 2-(furan-2-yl)benzimidazoles, derivatives of fuberidazole fungicide, with aryl bromides catalyzed by [RuCl2(cymene)]2/ pivalic acid system has been accomplished. High selectivity of the process may be accounted for by the action of benzimidazol-2-yl substituent as the directing group.
