실험 절차

To a stirring solution of 5-(3-(cyclopropylmethoxy)-2-hydroxy-4-methoxyphenyl)isobenzofuran-1(3H)-one (80 mg, 0.246 mmol) in acetonitrile (15 mL), was added potassium carbonate (101 mg, 0.736 mmol) and 3-bromomethyl-3-methoxymethyl-oxetane (95 mg, 0.490 mmol) and the resultant reaction mixture was heated to 70° C. for 16 h. The reaction mixture was cooled to RT and filtered through celite. The filtrate was concentrated under reduced pressure and the residue was purified by column chromatography (silica gel, 0-40% ethyl acetate in pet ether) to afford the title compound as a solid (30 mg, 28%).
