反応手順
106 g of 9A was suspended in 636 ml of water. 233 ml of ammonium hydroxide was added. 239.2 g of sodium dithionite was added over a period of about two hours at such a rate that the temperature of the reaction mixture was kept at about 50° C. The mixture was stirred at room temperature for two hours. The solid product was filtered, and extracted with methanol. Evaporation of the solvent from the extract gave 3,4-dichloro-6-aminophenol (9B).
