実験手順

To a solution of 2′-fluoro-5′-methoxy-3-(1-methoxy-3,3-dimethylbutyl)-[1,1′-biphenyl]-4-ol (290 mg) in THF (5.0 mL) were added triphenylphosphine (343 mg), ethyl 3-cyclopropyl-3-(3-(hydroxymethyl)phenyl)propanoate (325 mg) and a 40% solution of diethyl azodicarboxylate in toluene (600 μL), and the reaction mixture was stirred at room temperature for 2 hr. The reaction mixture was concentrated under reduced pressure and the residue was purified by silica gel column chromatography (ethyl acetate/hexane) to give the title compound (385 mg) as a colorless oil.
