Procedure

To a stirred mixture of methyl 5-fluoro-3-hydroxyphenylacetate (3.3 g, 15.7 mmol) and potassium carbonate (1.82 g, 50 mmol) in DMF (30 ml) was added methyl iodide (1.82 g, 50 mmol) at room temperature and the reaction mixture was stirred overnight. Then the mixture was diluted with water (50 ml) and extracted with ether. The combined extracts were washed with water and brine, dried (MgSO4) and concentrated in vacuo. The residue was purified by column chromatography (SiO2, 150 g; hexane/ethyl acetate (10/1)) afforded 495 mg (55%) of methyl 5-fluoro-3-methoxyphenylacetate as a colorless oil.
