実験手順

A solution of methyl 3-{4-[(4′-hydroxy-2′-methylbiphenyl-3-yl)methoxy]phenyl}propanoate (0.602 g, 1.60 mmol), 3-(pyridin-2-yl)propan-1-ol (0.822 g, 6.00 mmol) and triphenylphosphine (1.57 g, 6.00 mmol) in tetrahydrofuran (20 mL) under ice-cooling was stirred and diethyl azodicarboxylate (40% toluene solution, 2.72 mL, 6.00 mmol) was added. The mixture was warmed to room temperature and stirred for 42 hrs. The reaction mixture was concentrated under reduced pressure and the residue was purified by silica gel column chromatography (20%-60% ethyl acetate/hexane) and preparative HPLC to give the title compound as a yellow viscous oil (0.446 g, yield 56%).
