Reaction Steps

Under the nitrogen protection, 1.52 grams (0.0077 mole) of 5,8-dimethyl-5,10-dihydroindeno[1,2-b]indole is dissolved in 15 mL of toluene. To the solution is added 3.9 mL of n-butyllithium solution in pentane (2.0 mole/L). The mixture is refluxed for three hours and then cooled to 25° C. The precipitate is isolated by filtration, washed with hexane, and dried under vacuum, yielding 1.26 grams of 5,8-dimethyl-5,10-dihydroindeno [1,2-b]indolyllithium.
