To a stirring solution of 4-(4-(difluoromethoxy)-2-hydroxy-3-methoxyphenyl)-2,3-dihydro-1H-inden-1-one (75 mg, 0.234 mmol) in acetonitrile (10 mL) was added potassium carbonate (96 mg, 0.702 mmol) and ethyl iodide (109 mg, 0.702 mmol) and the resultant reaction mixture was heated to 80° C. for 4 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, 0-20% ethyl acetate in pet ether) to afford title compound as a solid (20 mg, 24%).
