Reaction Steps

Compound 6a,11a-dihydro-6H-benzo[4,5]furo[3,2-c]chromen-3-ol (100 mg, 0.42 mmol) was dissolved in DMF (5 ml) and NaH (10 mg, 0.42 mmol) was added to the solution at room temperature, followed by 1-(2-chloroethyl)piperidine hydrochloride (366 mg, 0.84 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 1-(2-(6a,11a-dihydro-6H-benzofuro[3,2-c]chromen-3-yloxy)ethyl)piperidine (102 mg, 70%) as white solid.
