A solution of (2-allyloxy-3-tert-butyl-5-methylphenyl)dimethylchlorosilane (7.0 mmol) in toluene (12.1 mL) was added dropwise to a solution of 1-dimethylamino-3,4-dimethylcyclopentadienyllithium (7.0 mmol) in tetrahydrofuran (10.5 mL) and the mixture was stirred at room temperature for 6 hours. After the solvent was distilled off under reduced pressure, dehydrated pentane was added and a precipitated solid was filtered off. The filtrate was concentrated to obtain the title compound (2.86 g, 100%) as an oil.
