实验步骤: 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. The solvent was eliminated by vacuum evaporation then dried on magnesium sulfate The solvent was eliminated by vacuum evaporation

实验步骤: To a stirred solution of 3-bromophenol (25 g, 145 mmol) in acetic anhydride (14 ml) was added a few drop of sulfuric acid, and the mixture was stirred for 2 hours. The mixture was poured into a solution of NaHCO3 (1.3 g, 15.5 mmol) in water (160 ml). The whole was extracted with diethylether. The organic layer was washed with saturated NaHCO3 aqueous solution, brine, dried over MgSO4, and concentrated in vacuo. The residue was used for next reaction without purification. (31 g, 99% yield). The whole was extracted with diethylether The organic layer was washed with saturated NaHCO3 aqueous solution, brine dried over MgSO4 concentrated in vacuo The residue was used for next reaction without purification

实验步骤: 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%). evaporated Ice was added the mixture was extracted with diethyl ether The organic phase was dried (MgSO4) evaporated

实验步骤: 3-Bromophenol (100 g, 580 mmol) and triethylamine (104 mL, 750 mmol) were dissolved in dichloromethane (500 mL), and the solution was cooled in an ice bath. Acetyl chloride (49.7 g, 630 mmol) was added dropwise. After 1 h the cooling bath was removed and the mixture was stirred overnight (approx 16 h) at room temperature. The mixture was washed with hydrochloric acid (1N, 250 mL), water (250 mL), 5% NaHCO3 (250 mL), and brine (250 mL). The organic layer was dried and evaporated to provide 124 g (99%) of 3-bromophenyl acetate as a light brown liquid; 1H NMR (CDCl3) δ7.36 (d, 1H), 7.32-7.20 (m, 2H), 7.05 (d, 1H), 2.28 (s, 3H). the solution was cooled in an ice bath After 1 h the cooling bath was removed The mixture was washed with hydrochloric acid (1N, 250 mL), water (250 mL), 5% NaHCO3 (250 mL), and brine (250 mL) The organic layer was dried evaporated
