Reaction Steps

N-(4b-hydroxy-7-isopropyl-10-oxo-4b,10-dihydro-9bH-indeno[1,2-b]benzofuran-9b-yl)acetamide (0.70 g, 2.07 mmol) was dissolved in anhydrous THF (15 ml). This solution was added with Ethyl chroloformate (0.32 g, 3.11 mmol) and Trimethylamine (0.25 g, 2.48 mmol). The reaction mixture was stirred for 4 hrs. After concentrating in a vacuum to remove THF, and the remainder was diluted with Methylene chrolide and washed with water many times. After drying and filtrating, the organic layer was purified using column chromatography (ethylacetate:hexane=1:4) to afford the title compound (0.64 g, 71%).
