Participants

Reaction Steps

Triethylamine (0.24 ml, 1.77 mmol) and methylchloroformate (0.11 ml, 1.48 mmol) were added to N-(4b-hydroxy-7-isopropyl-10-oxo-9b,10-dihydro-4bH-benzo[d]indeno[1,2-b]furan-9b-yl)acetamide (0.50 g, 1.48 mmol) in THF (5 ml). The reaction mixture was stirred at room temperature for 12 hrs, concentrated in a vacuum to remove solvent. The reaction mixture was extracted with water and methylene chloride, and purified through silica gel column chromatography (ethylacetate:hexane=1:2) to afford the title compound (0.10 g, 14%).
