Procedure

A mixture solution prepared by adding 15 g of reduced iron, 0.3 g of ammonium chloride and 50 ml of isopropyl alcohol to 10 g of 2,4-dimethoxy-5-nitrobenzenesulfonic acid obtained in Step (2) above, was heated at 70° to 80° C. on a water bath with stirring, and 50 ml of water was added thereto. After stirring at 80° C. for 1 hour, the mixture was filtered while hot. To the filtrate, 20 ml of hydrochloric acid (d=1.18) was added. The crystals thus-precipitated were collected by filtration and washed with 20 ml of iropropyl alcohol.
