Sulfonic acid ester derivatives represented by the general formula (4) or (5) are produced by reacting an amino alcohol derivative represented by the general formula (1) or (2) with an organic sulfonyl halide represented by the general formula (3), in a mixed solvent composed of an aprotic organic solvent and water in the presence of a non-water-prohibiting inorganic base. This procedure can be carried out in a simple, easy, safe and economical manner while reducing the load on the environment.
