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 3-bromomethyl-3-methyl-oxetane (123 mg, 0.75 mmol) and the resultant reaction mixture was heated to 80° 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, 0-40° A) ethyl acetate in pet ether) to afford title compound as a solid (30 mg, 30%).
