Versuchsvorschrift

4-(3′,5′-dimethylphenyl)-2-isopropylindene (5.5 g, 21 mmol) was dissolved in 80 mL of pentane. To this solution was added 8.3 mL of n-BuLi (2.5M in hexane) and the reaction was allowed to stir 4 hours at room temperature. A white solid precipitated from solution and was collected by frit filtration and washed with additional pentane. Yield was 3.3 g (60%).
