Procedure

A mixture of 5.2 g of sodium 2-chloro-5-nitrobenzenesulfonate, 0.6 g of manganese dioxide, 15 ml of 2-methoxyethanol, 1 ml of water and 0.95 g of sodium hydroxide was stirred at 75° C. for 40 minutes. After cooling, the insoluble materials were removed by filtration and the filtrate was poured into 100 ml of isopropyl alcohol. The crystals thus-precipitated were recovered by filtration to obtain 4.8 g of sodium 2-(2-methoxyethoxy)-5-nitrobenzenesulfonate. Melting Point: 238° to 239° C. The compound obtained by Method 2 was the same as that obtained by Method 1.
