To a stirring solution of 4-(3-(difluoromethoxy)-2-hydroxy-4-methoxyphenyl)-2,3-dihydro-1H-inden-1-one (80 mg, 0.25 mmol) in acetonitrile (10 mL) was added potassium carbonate (105 mg, 0.75 mmol) and 1-bromomethyl-4-methanesulfonyl-benzene (93 mg, 0.375 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 residue was purified by column chromatography (silica gel, 0-40% ethyl acetate in pet ether) to afford the title compound as a solid (25 mg, 20%).
