To a stirring solution of 5-(3-Hydroxy-2,4-dimethoxy-phenyl)-3H-isobenzofuran-1-one (80 mg, 0.279 mmol) in acetonitrile (10 mL) was added potassium carbonate (154 mg, 1.118 mmol) and 3-bromomethyl-3-methoxymethyl-oxetane (107 mg, 0.558 mmol) and the resultant reaction mixture was heated to 80° C. for 16 h. The reaction mixture was filtered through celite and the filtrate was concentrated under reduced pressure. The obtained residue was purified by column chromatography (silica gel, 0-50% ethyl acetate in pet ether) to afford the title compound as a solid (20 mg, 18%).
