20.1 g of 3-amino-4-phenoxyphenol was dissolved in 60 ml of acetic acid. 30 ml of acetic anhydride was added thereto with ice cooling. Stirring was conducted at 20°-25° C. for 1 hour. The mixture was subjected to distillation under reduced pressure to remove the solvent. The resulting crystal was recrystallized from toluene to obtain 22.6 g (yield: 93%) of 3-acetylamino-4-phenoxyphenol having a melting point of 151°-153° C.
