실험 절차

A solution of (3-fluoro-4-hydroxy-phenyl)-acetic acid (1.0 g, 5.87 mmol) in methanol (20 mL) was treated with a catalytic amount of sulfuric acid. The reaction was heated at 120° C. for 6 h. At this time, the reaction was concentrated in vacuo. Flash chromatography (Merck Silica gel 60, 230-400 mesh, 50/50 hexanes/ethyl acetate) afforded (3-fluoro-4-hydroxy-phenyl)-acetic acid methyl ester (1.05 g, 97.6%) as a white solid: mp 34-36° C.: EI-HRMS m/e calcd for C9H9FO3 (M+) 184.0535, found 184.0533.
