A　copper-mediated　three-component　reaction　of　o-iodoanilines,　anilines,　and　ethyl　trifluoropyruvate　is　reported.　The　transformation　allows　diverse　substrate　scope　on　both　o-iodoanilines　and　anilines,　delivering　various　2-trifluoromethylbenzimidazole　products　in　moderate　to　good　yields.　Mechanistic　studies　suggest　that　this　transformation　proceeds　via　condensation　of　o-iodoaniline　with　ethyl　trifluoropyruvate,　followed　by　an　intermolecular　Ullmann-type　cross-coupling　reaction　with　aniline　and　intramolecular　amination.
