Reaction Conditions

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 ethyl iodide (130 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, 57%).
