A general method for the N‐alkylation of NH‐sulfoximines and NH‐sulfondiimines has been developed, employing alkyl bromides with KOH in DMSO at room temperature. A variety of previously inaccessible N‐alkylated sulfoximines and sulfondiimines was prepared in good to excellent yields (up to 97%). As an application, the conditions were used to access the biologically active Suloxifen.
