Versuchsvorschrift

To a stirring solution of 4-(3-(cyclopropylmethoxy)-2-hydroxy-4-methoxyphenyl)-2,3-dihydro-1H-inden-1-one (80 mg, 0.246 mmol) in acetonitrile (10 mL) was added potassium carbonate (102 mg, 0.740 mmol) and ethyl iodide (153 mg, 0.984 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, 0-15% ethyl acetate in pet ether) to afford title compound as a solid (20 mg, 23%).
