Reaction Steps

Pyridine (64 μl, 0.80 mmol) was added to an ice cooled mixture of salicylic acid (10 mg, 0.72 mmol) and methylene chloride (10 mL). After 5 minutes, acetic anhydride (10 μl, 1.09 mmoles) was added. The resulting mixture was stirred at room temperature for 4 hrs. The product was extracted with methylene chloride and water. The organic layer was washed with brine, dried over Na2SO4 and concentrated under reduced pressure to afford 2-acetoxybenzoic acid in 76% yield.
