실험 절차

A mixture of 1.0 g (5.15 g) of 2,4-dihydroxy-3-propylacetophenone, 1.58 g (6.18 mmol) of methyl 4-bromomethylcinnamate and 0.85 g (6.18 mmol) of anhydrous potassium carbonate in 20 ml of acetone was stirred at reflux for 18 hours. Ether extraction gave 1.01 g of the title compound as a light yellow powder mp 121°-125° C.
