Reaction Steps

4b,9b-Dihydroxy-8-propyl-4bH-benzo[d]indeno[1,2-b]-furan-10(9bH)-one (0.80 g, 2.70 mmol) was dissolved in anhydrous THF (20 ml). This solution was added with anhydrous acetic acid (0.55 ml, 5.40 mmol), pyridine (0.21 ml, 2.7 mmol), and 4-dimethyl aminopyridine (0.08 g), and stirred at room temperature for 12 hrs. After the reaction mixture was extracted with dichloromethane, the organic layer was concentrated and purified using column chromatography (ethylacetate:hexane=1:4) to afford the title compound (0.85 g, 56%).
