Procedure

Under a nitrogen atmosphere, to a solution of 5-(2-fluoro-5-methoxyphenyl)-6-neopentylpyridin-2-ol (200 mg) and ethyl 3-cyclopropyl-3-(6-(hydroxymethyl)pyrimidin-4-yl)propanoate (173 mg) in THF (5.0 mL) were added 1,1′-(azodicarbonyl)dipiperidine (279 mg) and tributylphosphine (273 μL) at room temperature, and the mixture was stirred for 4 hr. The solvent was evaporated under reduced pressure and the residue was purified by silica gel column chromatography (ethyl acetate/hexane) to give the title compound (233 mg) as a colorless oil.
