By diazo transfer
In diazo transfer, sometimes called Regitz diazo transfer, certain carbon acids react with sulfonyl azides and a weak base like triethylamine or DBU, with corresponding sulfonamide byproduct. The mechanism involves enolate attack at the terminal nitrogen, proton transfer, and sulfonamide anion expulsion.
