To a solution of 3.41 g (15.0 mmol) of 7-bromo-5-fluoro-2-methyl-1H-indene in 80 ml of ether, 6.00 ml (15.0 mmol) of 2.5 M nBuLi in hexanes was added. The reaction mixture was stirred for 12 h at room temperature; then, this solution was added dropwise to a solution of 3.88 g (15.0 mmol) of (9H-fluoren-9-yl)chlorodimethylsilane in 80 ml of ether over 1 h at room temperature. The resulting mixture was stirred for 12 h, and then 100 ml of water was added. The organic layer was separated, dried over Na2SO4, and evaporated to dryness. The product was isolated by flash chromatography on Silica Gel 60 (40-63 um, d 30 mm, l 400 mm, eluent: hexanes). Yield 3.71 g (55%).
