실험 절차

To a stirring solution of 4-(3-hydroxy-2,4-dimethoxyphenyl)-2,3-dihydro-1H-inden-1-one (80 mg, 0.281 mmol) in acetonitrile (5 mL) was added potassium carbonate (115 mg, 0.843 mmol) and 3-(bromomethyl)-3-methyloxetane (139 mg, 0.843 mmol) and the resultant reaction mixture was heated to 80° C. for 4 h. The reaction mixture was filtered through celite and the filtrate was concentrated under reduced pressure. The obtained residue was purified by column chromatography (silica gel, 0-50% ethyl acetate in pet ether) to afford the title compound as a solid (40 mg, 38.5%).
