実験手順

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 (10 mL) was added potassium carbonate (155 mg, 1.124 mmol) and 3-bromo-2,2-dimethyl-propan-1-ol (141 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 (20 mg, 20%).
