Reaction Steps

To a stirring solution of 5-(4-(difluoromethoxy)-2-hydroxy-3-methoxyphenyl)isobenzofuran-1(3H)-one (80 mg, 0.25 mmol) in acetonitrile (10 mL) was added potassium carbonate (103.5 mg, 0.75 mmol) and ethyl iodide (0.1 mL, 0.75 mmol) and the resultant reaction mixture was heated to 70° C. for 3 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, 100-200 mesh, 0-30% ethyl acetate in pet ether) to afford title compound as a solid (50 mg, 58%).
