실험 절차

4-Hydroxy-2-methoxybenzaldehyde (2.0 g, 13.15 mmol), benzyl bromide (3.14 mL, 26.3 mmol) and potassium carbonate (3.63 g, 26.3 mmol) are combined in acetone (5 mL) and the mixture is stirred for 4 hours. The mixture is concentrated under vacuum, suspended in dichloromethane and washed with water. The organic phase is concentrated under vacuum and the residue purified by flash chromatography (10% ethyl acetate in cyclohexane) to give the title compound (yield 2.0 g).
