2-Fluoro-3-methoxypyridine (3): 2-Fluoropyridin-3-ol (10 mmol),methyl iodide (20 mmol) and potassium carbonate (20 mmol) in acetone (100 ml) was refluxed overnight. The inorganic salt wasfiltered and the solvent was evaporated. The residue was purified oncolumn (eluent: EtOAc:hexane = 1:5) to afford a colorless liquid [19](95%). 1H NMR (CDCl3): d 7.74-7.75 (m, 1H, C6-H), 7.26-7.31 (m, 1H,C4-H), 7.11-7.15 (m, 1H, C5-H), 3.91 (s, 3H, OMe). 19F NMR (CDCl3): d90.15 (s). ESI-MS: 128 (M+1)+.
