Reaction Steps
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 (115 mg, 0.837 mmol) and 3-bromomethyl-3-methyl-oxetane (138 mg, 0.837 mmol) and the resultant reaction mixture was heated to 80° C. for 4 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 (50 mg, 48.4%).
