Versuchsvorschrift

1-Oxo-3-phenyl-6-(3-phenyl-propoxy)-1H-indene-2-carboxylic acid ethyl ester (350 mg, 0.85 mmol) obtained in Step 1 was dissolved in THF, and phenylmagnesium chloride (0.064 mL, 0.93 mmol) was added thereto, followed by stirring for 1 hr at 0° C. The resulting 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 475 mg of the titled compound (yield: 100%).
