실험 절차

3-Benzyloxy-5-hydroxybenzoic acid (2.16 g) and acetic anhydride (15 mL) were suspended in acetic acid (15 mL), and the resulting mixture was stirred at 120° C. for 24 hours. The reaction mixture was concentrated under reduced pressure and the residue obtained was purified by column chromatography on silica gel (eluent: ethyl acetate/hexane=1/1 to 1/0) to give the title compound (1.74 g).
