10 g of tetrahydofluorene (59 mmol) was dissolved in 75 ml of pentane. To this solution 21 ml of n-butyl lithium (n-BuLi) (2.65M) was added dropwise over a 20 min period. The solution was stirred overnight with deposition of a white solid. The solid was collected by filtration, washed with pentane and dried under reduced pressure to give 7.14 g (70 percent yield) of product.
