7,9 dimethylbicyclo-[4.3.0]-nona-1(6),7-diene (5.0 g, 33.5 mmol) was added to 100 mL of pentane. To this solution nBuLi (2.7M, 13 mL) was added dropwise, and the mixture was stirred for 12 hours. The resulting white precipitate was collected via filtration, washed with pentane and dried under reduced pressure to give 5.02 g (97 percent) of product.
