Reaction Steps

Compound 4-methyl-6a,11a-dihydro-6H-benzo[4,5]furo[3,2-c]chromen-3-ol (100 mg, 0.34 mmol) was dissolved in DMF (5 ml) and NaH (8.1 mg, 0.34 mmol) was added to the solution at room temperature, followed by allyl bromide (0.06 ml, 0.68 mmol). The reaction mixture was stirred at room temperature to 6 hours and poured into iced water and neutralized with 10% HCl to get the white precipitate. Precipitate were washed with water and purified by silica gel column chromatography using hexane-chloroform as the eluent to give 3-isopropoxy-6a,11a-dihydro-6H-benzofuro[3,2-c]chromene (58 mg, 50%) as white solid.
