Reaction Steps

5-Acetylsalicylic acid (200 mg), 1-ethyl-3-(3-dimethylaminopropylcarbodiimide hydrochloride (382 mg), 1-hydroxybenzotriazole hydrate (306 mg), and ethanol (2 ml) were dissolved in N,N-dimethylformamide to prepare a solution which was then stirred at room temperature overnight. Water was added to the reaction solution, and the mixture was extracted with ethyl acetate. The ethyl acetate layer was then washed with water and was dried over anhydrous sodium sulfate. The solvent was removed therefrom by distillation under the reduced pressure, and the residue was purified by column chromatography using acetone-hexane to give ethyl 5-acetylsalicylate (211 mg, yield 92%).
