Reaction Steps

N-(4b-hydroxy-7-isopropyl-10-oxo-4b,10-dihydro-5-oxa-indeno[2,1-a]inden-9b-yl)-acetamide (0.50 g, 1.48 mmol) was dissolved in anhydrous THF (15 ml). This solution was added with Dimethyl-carbamylchrolide (0.23 g, 2.22 mmol), Trimethylamine (0.17 g, 1.77 mmol). The reaction mixture was heated for 24 hrs under reflux. After concentrating in a vacuum to remove THF, and the remainder was diluted with Ethylacetate and washed with Bicarbonate sodium aqueous solution many times. After drying and filtrating, the organic layer was purified using column chromatography (ethylacetate:hexane=1:1) to afford the title compound (0.26 g, 43%).
