実験手順

2′,4′-Dihydroxyacetophenone (11.71 g, 0.077 mol), 4-methoxybenzyl chloride (10.44 ml, 0.077 mol), anhydrous potassium carbonate (11.75 g, 0.085 mol) and potassium iodide (12.78 g, 0.077 mol) are heated together in refluxing dry acetone (80 ml) for 4 hours. The mixture is then cooled to room temperature, poured into water (250 ml) and extracted with ethyl acetate (3×100 ml). The ethyl acetate extracts are combined, washed with saturated brine (100 ml), dried (MgSO4), filtered and concentrated, until crystallization commences. After standing at 4° C. for 16 h, the crystals are recovered by filtration, washed with cold ethyl acetate and then with n-hexane and dried.
