Procedure

Under a nitrogen atmosphere, to a solution of 6-(2-fluoro-5-methoxyphenyl)-5-neopentylpyridin-3-ol (300 mg), ethyl 3-cyclopropyl-3-(3-(hydroxymethyl)phenyl)propanoate (257 mg) and triphenylphosphine (554 mg) in THF (5.0 mL) was added a 40% solution of diethyl azodicarboxylate in toluene (943 μL) at room temperature, and the mixture was stirred for 14 hr. The solvent of the reaction mixture was evaporated under reduced pressure and the residue was purified by silica gel column chromatography (ethyl acetate/hexane) to give the title compound (253 mg) as a yellow oil.
