To a stirring solution of 5-(3-(difluoromethoxy)-2-hydroxy-4-methoxyphenyl)isobenzofuran-1(3H)-one (80 mg, 0.246 mmol) in acetonitrile (10 mL) was added potassium carbonate (102 mg, 0.738 mmol) and propyl bromide (60 mg, 0.492 mmol) and the resultant reaction mixture was heated to 70° C. for 16 h. The reaction mixture was cooled to RT, filtered through celite and the filtrate was concentrated under reduced pressure. The obtained residue was purified by column chromatography (silica gel, 0-20% ethyl acetate in pet ether) to afford the title compound as a solid (20 mg, 22%).
