実験手順

Concentrated sulphuric acid (2 ml) was added to a stirred mixture of 3-bromophenol (67 g) and acetic anhydride (20 ml). The mixture was stirred at ambient temperature for 4 hours and evaporated. Ice was added and the mixture was extracted with diethyl ether. The organic phase was dried (MgSO4) and evaporated to give 3-bromophenyl acetate (75.4 g, 90%).
