A 100 mL Schlenk flask is charged with diethyl ether, 50 mL, and n-butyllithium, 5.22 mL (14.67 mmole) of a 2.81M solution in hexane, at -78° C. To the magnetically stirred, chilled solution is added nitrogen degassed indene, 1.70 g (14.6 mmole). The mixture is stirred and warmed to room temperature over 1 to 2 hours. The solution is stirred at least an additional 4 hours at room temperature to insure complete reaction prior to further use.
