A 100 mL Schlenk flask is charged with diethyl ether, 50 mL, and n-butyllithium, 5.2 mL (13.88 mmole) of a 2.68M solution in hexane) at -78° C. To the magnetically stirred, chilled solution is added nitrogen degassed indene, 1.8 mL (15.27 mmole). The mixture is stirred and warmed to room temperature over 1 to 2 hours. The mixture is stirred at least an additional 4 hours at room temperature to insure complete reaction prior to further use.
