実験手順

To a solution of 6-(chloromethyl)-2-(2,2-dimethylpropyl)-3-(2-fluoro-5-methoxyphenyl)pyridine (330 mg) in acetonitrile (8.0 mL) were added ethyl 3-(5-hydroxy-2-methoxyphenyl)propanoate (216 mg) and cesium carbonate (647 mg), and the mixture was heated under reflux for 15 hr. Ethyl acetate was added to the reaction mixture, and the insoluble material was filtered off. The solvent in the filtrate was evaporated under reduced pressure, and the residue was purified by silica gel column chromatography (ethyl acetate/hexane) to give the title compound (290 mg) as a white solid.
