Reaction Steps

To 35 ml of a 0.4N aqueous solution of sodium hydroxide were added 1.70 g (7.17 mmol) of 2-methyl-4-methoxy-5-acetylaminophenyl acetate and 10 ml of ethanol. The mixture was stirred at room temperature for 10 minutes. When crystals were completely dissolved, the stirring was ceased. Then 0.3 ml of acetic acid was added and thus crystals were precipitated. The crystals were collected by filtration, purified by column chromatography (Silica Gel 60, trade name, manufactured by Merck Co., 230-400 mesh, 200 g, eluent: ethyl acetate) and recrystallized from the solvent mixture of ethyl acetate/hexane (2:1). Thus 1.05 g (5.38 mmol) of 2-methyl-4-methoxy-5-acetylaminophenol was obtained. The yield was 75%.
