실험 절차

A solution of methyl 3-(4-hydroxyphenyl)propanoate (0.396 g, 2.20 mmol), [3-(3-methylphenoxy)phenyl]methanol (0.429 g, 2.00 mmol) and tributylphosphine (0.747 mL, 3.00 mmol) in toluene (30 mL) was stirred under ice-cooling, 1,1′-(azodicarbonyl)dipiperidine (0.757 g, 3.00 mmol) was added by small portions, the temperature was raised to room temperature and the mixture was stirred for 18 hrs. Hexane (15 mL) was added to the reaction mixture, the precipitated insoluble material was filtered off, and the filtrate was concentrated under reduced pressure. The residue was purified by silica gel chromatography (hexane-20% ethyl acetate/hexane) and preparative HPLC (10-95% acetonitrile/water, containing 0.1% trifluoroacetic acid) to give the title compound (0.414 g, yield 55%) as a pale-yellow oil.
