실험 절차
To a solution of sodium ethoxide (10.8 g) in ethanol (500 ml), 2-(2-hydroxyphenyl)ethanol (20.0 g) and benzyl bromide (24.8 g) were added and the mixture was refluxed under heating for 2 hours. The solvent was distilled away under reduced pressure, water was added thereto and the mixture was extracted with ethyl acetate. The organic layer was washed with a 2M aqueous potassium hydroxide solution and a saturated brine and dried over sodium sulfate. The solvent was distilled away under reduced pressure and the residue was subjected to silica gel chromatography (eluent; hexane-ethyl acetate=8:1) to give the subject compound (27.2 g).
