Reaction Steps

4b, 9b-dihydroxy-7-isopropyl-2-methoxy-4bH-benzo[d]indeno[1,2-b]furan-10(9bH)-one (0.30 g, 0.91 mmol) was completely dissolved in anhydrous THF (10 ml). This solution was added with anhydrous acetic acid (0.18 g, 1.82 mmol), pyridine (0.07 g, 0.91 mmol) and DMAP (0.03 g), and stirred at room temperature. The reaction mixture was concentrated, and extracted with ethylacetate, and the concentrated organic layer was purified using column chromatography (ethylacetate:hexane=1:3) to afford the title compound (0.19 g, 51%).
