Acetyl chloride → Phenol, 4-bromo-, 1-acetate

참여 물질

반응 단계

Anhydrous aluminum chloride (84 g, 0.486 mol) was suspended in methylene chloride (1200 mL), and then acetyl chloride (49.2 g, 0.629 mol) was added while stirring and cooling on ice. The mixture was stirred for 20 minutes while cooling on ice and 4-bromophenol (98 g, 0.57 mol) was added. The reaction mixture was stirred at room temperature for 1 h, and then ice water was added and extraction was performed with ethyl acetate. The organic layer was washed with brine and then dried over anhydrous sodium sulfate. After distilling off the solvent under reduced pressure, the residue was purified by silica gel column chromatography to yield 4-bromophenyl acetate (104 g, 85%). 1H-NMR (CDCl3): 2.28 (s, 3H), 6.98 (d, 2H), 7.48 (d, 2H).
