Procedure

3-bromophenol was dissolved in dichloromethane. Triethylamine (1 eq) and acetic anhydride (2 eq) were added and the mixture was stirred at room temperature for 5 hours. The solvent was eliminated by vacuum evaporation. The evaporation residue was taken up in dichloromethane then dried on magnesium sulfate. The solvent was eliminated by vacuum evaporation.
