Under a nitrogen atmosphere, to a solution of (6-(2-fluoro-5-methoxyphenyl)-5-((tetrahydro-2H-pyran-2-yl)oxy)pyridin-3-yl)methanol (189 mg) and ethyl 3-(6-chloropyrimidin-4-yl)-3-cyclopropylpropanoate (174 mg) in THF (2.8 mL) was added 60% sodium hydride (25 mg) at 0° C., and the mixture was stirred at room temperature for 2 hr. The reaction mixture was cooled to 0° C., and neutralized with 1N hydrochloric acid. The reaction mixture was extracted with ethyl acetate, and the extract was washed with saturated brine, and dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure and the residue was purified by silica gel column chromatography (ethyl acetate/hexane and then methanol/ethyl acetate) to give the title compound (164 mg) as a colorless oil.
