실험 절차

A solution of 5-hydroxy-[1,1′-biphenyl]-2-carbaldehyde (651) (292 mg, 1.47 mmol) and (carboxymethylene)-triphenylphosphorane (564.5 mg, 1.62 mmol) in toluene (15 mL) was refluxed for 24 hours. The reaction was concentrated in vacuo and was purified by flash column chromatography on silica gel with hexanes and EtOAc (30%) to give (E)-ethyl 3-(5-hydroxy-[1,1′-biphenyl]-2-yl)acrylate (652).
