A 20 g (182 mmol) solution of indenyl lithium in tetrahydrofurane was added to a solution of 41 g (182 mmol) of 2-bromo-1-tertbutylamino-1,1-dimethylsilaethane at 0° C. After the reaction was concentrated to dryness and the residue was extracted with hexane. Finally, the solution in hexane was concentrated to the obtainment of an orange oil: 13.5 g (52 mmol, yield: 29%). 1H-NMR (CDCl3): 7.50(m,1H), 7.39(m,1H), 7.35(m,1H), 7.23(m,1H), 6.17(m,1H), 3.42(m,2H), 2.17(m,2H), 1.22(m,9H), 0.20(m,6H).
