実験手順

To a solution of 3-(2′-fluoro-4-hydroxy-5′-methoxybiphenyl-2-yl)-2,2-dimethylpropanenitrile (151 mg), ethyl 3-cyclopropyl-3-(2-(hydroxymethyl)pyridin-4-yl)propanoate (168 mg) and tributylphosphine (0.25 mL) in toluene (5.0 mL) was added 1,1′-(azodicarbonyl)dipiperidine (256 mg), and the mixture was stirred at room temperature for 3 hr. Hexane was added to the reaction mixture, and the mixture was filtered through celite. The filtrate was concentrated under reduced pressure and the residue was purified by silica gel column chromatography (ethyl acetate/hexane) to give the title compound (234 mg) as a colorless oil.
