실험 절차

To a stirring solution of 4-(3-(difluoromethoxy)-2-hydroxy-4-methoxyphenyl)-2,3-dihydro-1H-inden-1-one (80 mg, 0.25 mmol) in acetonitrile (10 mL) was added potassium carbonate (138 mg, 0.75 mmol) and 3-bromomethyl-3-methoxymethyl-oxetane (97.5 mg, 0.5 mmol) and the resultant reaction mixture was heated to 70° C. for 16 h. The reaction mixture was cooled to RT, filtered through celite and the filtrate was concentrated under reduced pressure. The residue was purified by column chromatography (silica gel, 0-40% ethyl acetate in pet ether) to afford title compound as a solid (20 mg, 18%).
