실험 절차

To a solution of 4-phenylphenol (1 eq) in acetone, K2CO3 (2 eq) and alkyl bromide (1.2 eq) were added and the mixture reaction was stirred at 55° C. overnight. Quenched with water and extracted with ethyl acetate. The organic layer was dried (MgSO4) and concentrated to give 4-allyloxybiphenyl. This crude product was dissolved in Me2NPh and heated to reflux for 6 hours and then stirred at room temperature over 3 days. Refluxed again for 8 hours and then poured into and ice-cold HCl 1M solution, extracted with ethyl acetate and washed with water. Dried and concentrated to give a crude product which was purified by chromatography to give the title product.
