Under a nitrogen atmosphere, to a solution of 2′-fluoro-5′-methoxy-2-neopentyl-[1,1′-biphenyl]-4-ol (100 mg), ethyl 3-cyclopropyl-3-(2-(hydroxymethyl)pyridin-4-yl)propanoate (94 mg) and triphenylphosphine (182 mg) in THF (3.0 mL) was added a 40% solution of diethyl azodicarboxylate in toluene (315 μL) at room temperature, and the mixture was stirred for 14 hr. Triphenylphosphine (182 mg) and a 40% solution of diethyl azodicarboxylate in toluene (315 μL) were added to the reaction mixture, and the mixture was further stirred at room temperature 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 (71 mg) as a pink oil.
