Reaction Steps

Under an argon atmosphere, to a solution of 6-(2-fluoro-5-methoxyphenyl)-5-neopentylpyridin-3-ol (300 mg), ethyl 3-cyclopropyl-3-(2-(hydroxymethyl)pyridin-4-yl)propanoate (259 mg) and triphenylphosphine (544 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 (NH, ethyl acetate/hexane) to give the title compound (182 mg) as a pale-orange oil.
