Procedure

Under a nitrogen atmosphere, to a solution of 5-(2-fluoro-5-methoxyphenyl)-6-neopentylpyridin-2-ol (100 mg) and ethyl 3-cyclopropyl-3-(2-(hydroxymethyl)pyridin-4-yl)propanoate (94 mg) in THF (3.0 mL) were added 1,1′-(azodicarbonyl)dipiperidine (140 mg) and tributylphosphine (136 μL), and the mixture was stirred at room temperature for 14 hr. The solvent was evaporated under reduced pressure and the residue was purified by silica gel column chromatography (NH, ethyl acetate/hexane) to give the title compound (140 mg) as a colorless oil.
