참여 물질

반응 단계

To a solution of methyl (6-hydroxy-1-benzofuran-3-yl)acetate (10.0 g, 48.5 mmol) in DMF (100 mL) were added 1-(chloromethyl)-4-ethoxybenzene (12.4 g, 72.7 mmol) and potassium carbonate (13.5 g, 97.0 mmol), and the mixture was stirred at room temperature for 3 hr. Water was added to the reaction mixture, and the mixture was extracted with ethyl acetate. The extract was washed twice with saturated brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure and the residue was washed with diethyl ether and hexane to give the title compound (15.8 g, yield 96%) as a white solid.
