5,6-Dimethoxy-indene (4.82 g, 27.35 mmol) was dissolved in a mixture of 20 mL of toluene and 180 mL of hexane and 16.25 mL of 1.6 M n-BuLi were added dropwise via a syringe over a 5 min period forming a white precipitate. The reaction mixture was stirred for 4 h then filtered. The solids were washed with 60 mL of hexane and allowed to dry under reduced pressure to afford the desired anion as a light pink solid (4.62 g, 98 percent yield).
