الإجراء التجريبي

2-Bromo-3-phenyl-6-(3-phenyl-propoxy)-indene-1-one (1.0 g, 2.3 mmol) obtained in Step 2 was dissolved in N,N-dimethyl formamide (10 mL), copper(I) cyamide (617 mg, 6.9 mmol) was added thereto, and the mixture was stirred for 3 hrs at 150° C., followed by cooling. The resulting mixture was washed with saturated ammonium chloride 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 (ethyl acetate:hexane=1:3) to obtain 700 mg of the titled compound (yield: 80%) as a red solid.
