الإجراء التجريبي

6-Hydroxy-1-oxo-3-phenyl-1H-indene-2-carboxylate ethyl ester (1.7 g, 6.07 mmol), 3-phenylpropanol (1.65 g, 12.14 mmol) and triphenylphosphine (3.18 g, 12.14 mmol) were dissolved in tetrahydrofuran (100 ml). Diethyl azodicarboxylate (2 ml, 12.14 mmol) dissolved in tetrahydrofuran (20 ml) was added dropwise thereto at 0° C. After stirring for 6 hours at room temperature, the mixture was washed with brine, extracted with ethyl acetate, the extract was dried over anhydrous magnesium sulfate, the concentrated under a reduced pressure, and the residue was purified by silica gel column chromatography (diethyl ether:hexane=1:10) to obtain the title compound (yield 85%) as a dark red solid.
