반응 단계
A mixture of 10 g of sodium 2-(2-propoxyethoxy)-5-nitrobenzenesulfonate, 5 g of reduced iron, 0.2 g of ammonium chloride, 20 ml of isopropyl alcohol and 20 ml of water was stirred at 77° C. for 2 hours. After the reaction was completed, the reaction solution was filtered to remove insoluble products. After addition of 10 ml of concentrated hydrochloric acid (36%), the filtrate was cooled. Precipitated crystals were collected by filtration and dried by air. Yield: 7.1 g.
