4-(2-methylphenyl)-2-isopropylindene (6.6 g, 26.5 mmol) was dissolved in 80 mL of pentane. To this solution was added 10.6 mL of n-BuLi (2.5M in hexane) and the reaction was allowed to stir 4 hours at room temperature. A white solid precipitates from solution and was collected by frit filtration and washed with additional pentane. Yield was 5.8 g (88%).
