Versuchsvorschrift

To a suspension of 4-amino-2,5-dimethyl-phenol (6.85 g, 50 mmol) in 30 mL of water was added acetic anhydride (5.67 mL, 60 mmol). The mixture was vigorously stirred at 70° C. for 20 min and then cooled down to room temperature. The solid was collected by filtration and washed with water to give N-(4-hydroxy-2,5-dimethyl-phenyl)-acetamide as gray solid (8.1 g, 90%).
