A simple and practical protocol for the cross‐coupling of methanesulfonamide and aryl iodides under ligand‐free copper(I)‐oxide‐catalyzed conditions in water is reported. The method allows the preparation of a wide variety of synthetically useful N‐arylated methanesulfonamides in good to excellent yields (up to 90 %) under the optimized conditions.
