4-[3′,5′-bis(trifluoromethyl)phenyl]-2-methylindene (2.2 g, 6.5 mmol) was dissolved in 50 mL of pentane. To this solution was added 2.6 mL of n-BuLi (2.5M in hexane) and the reaction was allowed to stir 4 hours at room temperature. A yellow-white-solid precipitated from solution and was collected by frit filtration and washed with additional pentane. Yield was 1.6 g (73%).
