実験手順

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 were mixed and stirred at 75° C. for 40 minutes. After cooling, insolubles were filtered, and the filtrate was poured into 100 ml of isopropyl alcohol. Crystals thus formed were collected by filtration to obtain 4.8 g of sodium 2-(2-methoxyethoxy)-5-nitrobenzenesulfonate. m.p. 238° to 239° C.
