Reaction Steps
193.1 g of 7A was mixed with 1400 ml of water. 513 ml of ammonium hydroxide was added. 595 g of powdered sodium dithionite was added in portions over a period of 50 minutes. The resulting mixture was stirred for 2 hours. The solid product was collected and dried under vacuum over P2O5 to give 4-methoxy-2-aminophenol (7B), mp: 134°-136° C.
