Vorschrift

6-Methoxy-1-oxo-3-phenyl-1H-indene-2-carboxylic acid ethyl ester (100 mg, 0.325 mmol) obtained in Example 1 was dissolved in THF and 1.5 equivalents of 3-methoxyphenylmagnesium bromide were added thereto, followed by stirring for 1 hr at 0° C. Then, the reaction mixture washed with saturated saline and extracted with ethyl acetate. The organic layer was separated, dried over anhydrous MgSO4, and concentrated under a reduced pressure. The resulting residue was purified by flash chromatography to obtain 122 mg of the titled compound (yield: 90.4%).
