Procedure

A mixed solution consisting of 30 g of 2-(2-methoxyethoxy)-5-nitrobenzenesulfonic acid, 30 g of reducing iron, 0.6 g of ammonium chloride and 60 ml of water was kept at a temperature of 80° to 85° C. over a period of 2 hours with stirring. After the completion of the reaction, the insoluble substances were removed by filtration. To the filtrate was added 200 ml of isopropyl alcohol and the mixture was cooled with ice. The crystals thus precipitated were recovered, washed with 50 ml of isopropyl alcohol and air-dried. Yield 23 g m.p. 250° C. or above.
