4-Chlorophenol → 4-Chlorophenyl Acetate

Participants

Reaction Steps

Acetic anhydride (80.1 g, 0.78 mol) and one drop of concentrated sulfuric acid were added to 4-chlorophenol [compound (6-1)] (100 g, 0.78 mol) at room temperature, and the mixture was stirred for 17 hours. The resultant mixture was added to ice-water, and converted to alkaline by the addition of sodium hydroxide (20% aqueous solution), followed by extraction with diethyl ether. The organic layer was washed with water, dried over magnesium sulfate. Subsequently, the solvent was removed under reduced pressure, and then the residue was subjected to distillation under reduced pressure (81° C./1.5 mmHg), to thereby yield 4-chlorophenyl acetate as a colorless oily product (130 g, yield: 98.0%).
