Procedure

To a solution of 6-(chloromethyl)-2-(2,2-dimethylpropyl)-3-(2-fluoro-5-methoxyphenyl)pyridine (321 mg) in acetonitrile (10 mL) were added ethyl 3-(2-fluoro-3-hydroxyphenyl)propanoate (430 mg) and cesium carbonate (980 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. The residue was purified by silica gel column chromatography (ethyl acetate/hexane) to give the title compound (350 mg) as a white solid.
