Reaction Steps

4-Amino-3-trifluoromethylphenol (0.212 g; 1.2 mmol) was dissolved in 10 ml of glacial acetic acid under nitrogen atmosphere and acetic anhydride (0.3 ml; 3.0 mmol) was added followed with stirring for an hour at room temperature. Water (0.5 ml) was added into the reaction mixture and then evaporated to dryness. Toluene (50 ml) was added and the evaporation was repeated to give a quantitative yield of pure N-(4-Hydroxy-2-trifluoromethylphenyl)acetamide. 1H NMR (400 MHz, DMSO-d6): 1.99 (3H, s), 7.01 (1H, dd, J=8.6 Hz, J=2.6 Hz), 7.02 (1H, d, J=2.5 Hz), 7.19 (1H, d, J=8.4 Hz), 9.33 (1H, s), 10.08 (1H, br s).
