Procedure
A mixture consisting of 5.2 g of sodium 2-chloro-5-nitrobenzenesulfonate, 0.6 g of manganese dioxide, 15 ml of methyl cellosolve, 1 ml of water and 0.95 g of sodium hydroxide was stirred at 75° C. for 40 minutes. After cooling, insoluble substances 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 of sodium 2-(2-methoxyethoxy)-5-nitrobenzenesulfonate. m.p. 238°-239° C.
