A copper-catalyzed, practical, and straightforward one-pot synthesis of multisubstituted imidazoles in good yields from arylacetic acids, N-arylbenzamidines, and nitroalkanes involves simultaneous activation of C–H and N–H bonds. The use of inexpensive copper sulfate as a catalyst and readily available starting materials makes this protocol economically viable.
