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.

Wherein n represents an integer of 0 to 5, A represents a phenyl group, which may be substituted, R represents a methanesulfonyl, ethanesulfonyl, p-toluenesulfonyl or p-nitrobenzenesulfonyl group and X represents a chloride, bromine or iodine atom.
通用公式(4)或(5)所代表的磺酸酯衍生物是通过将通用公式(1)或(2)所代表的氨基醇衍生物与通用公式(3)所代表的有机磺酰卤反应,在由无水无机碱存在的无水有机溶剂和水组成的混合溶剂中进行生产的。这种方法可以在简单、容易、安全和经济的情况下进行,同时减少对环境的负荷。
其中n表示0到5的整数,A表示苯基,可以是取代的,R表示甲磺酰基、乙磺酰基、对甲苯磺酰基或对硝基苯磺酰基,X表示氯、溴或碘原子。
