Procedure

To a solution of 6-(chloromethyl)-2-(2,2-dimethylpropyl)-3-(2-fluoro-5-methoxyphenyl)pyridine (320 mg) in acetonitrile (10 mL) were added ethyl 3-(5-hydroxy-2-methylphenyl)propanoate (230 mg) and cesium carbonate (546 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 (427 mg) as a colorless oil.
