Beschreibung
Zusammenfassung:	A compound having at least one -SO2CH2CH2OSO3M group in the molecule, wherein M is hydrogen or an alkali metal, which is useful as a reactive dye for dying cellulose fiber materials or as an intermediate for production of said reactive dye, is industrially advantageously produced in a high yield and a high quality by esterification of a compound having at least one -SO2CH2CH2OH in the molecule using a sulfuric acid-esterifying agent in the presence of a water-insoluble organic solvent and a secondary or tertiary amine.
