実験手順
336.4 g of 2-nitro-4-methoxyaniline was refluxed with 200 g of sodium hydroxide and 10 g of arsenic trioxide in 6500 ml of water, for 20 hours. The resulting solution was cooled on an ice-bath, acidified to pH 1 with concentrated hydrochloric acid and filtered. The solid product was washed with water, and dried under vacuum and in the presence of P2O5 to give 4-methoxy-2-nitrophenol (7A), mp: 78°-80° C.
