Reaction Steps

A solution of 2,4-dihydroxyacetophenone (1.1 g, 7.24 mmol). 4-hydroxyphenylacetic acid (1.45 g, 9.5 mmol) and potassium acetate (0.9 g. 9.2 mmol) in acetic anhydride (10 mL) was heated under reflux for 18 h. After cooling, the mixture was poured into ice and water. The solid was filtered, washed with ether and dried under vacuum to give 3-(4-acetoxyphenyl)-7-acetoxy-4-methylcoumarin (1.83 g).
