| description | 3-Aminophenyl 2-hydroxyethyl sulphone (I) can be prepared in a high yield and purity by treating 2-chloro-5-nitrophenyl 2-hydroxyethyl sulphone (II) or 4-chloro-3-nitrophenyl 2-hydroxyethyl sulphone (III) with hydrogen in the presence of hydrogenation catalysts in an aqueous or aqueous organic medium. (II) is obtained by reducing 2-chloro-5-nitrobenzenesulphochloride with sodium sulphite and subsequently reacting the product with ethylene oxide. |
