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

関与物質

反応手順

Anhydrous aluminum chloride (21 g) was suspended in methylene chloride (300 mL), and then acetyl chloride (12.3 g) was added while stirring and cooling on ice. The mixture was stirred for 10 minutes while cooling on ice and 4-bromophenol (24.5 g) was added. The reaction mixture was stirred at room temperature for 1 hour, 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 magnesium sulfate. After distilling off the solvent under reduced pressure, the residue was purified by silica gel column chromatography (solvent: n-hexane-ethyl acetate) to yield the title compound (23.9 g) as an oil.
