Reaction Steps
To a solution of methyl 6-(2-fluoro-5-methoxyphenyl)-5-hydroxynicotinate (739 mg) and 4-(bromomethyl)-2,2-dimethyltetrahydro-2H-pyran (828 mg) in DMF (20 mL) was added potassium carbonate (736 mg), and the mixture was stirred at room temperature for 2 hr. The reaction mixture was poured into water (100 mL), and the mixture was extracted with ethyl acetate. The extract was dried over anhydrous sodium sulfate and the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate/petroleum ether) to give the title compound (950 mg) as a colorless oil.
