Reaction Steps

7.24 g of 2,4,7 trimethylindene (45.8 mmol) were suspended in 70 ml of Et2O, cooled to 0° C., and to it were added 19.2 ml of a 2.5 M BuLi solution in hexane (48.0 mmol) with stirring. A slightly yellow cream is obtained. After allowing the reaction mixture to reach ambient temperature, additional 10 ml of Et2O were added, to improve stirring. After about 1 h the mixture was cooled again to 0° C. and 7.20 g of Me2SiCl2 (55.2 mmol, 1.2 eq) in 30 ml di THF, previously cooled to 0° C., were added to it. At the end of the addition, the reaction mixture was allowed to reach ambient temperature. At this point the reaction mixture, which appeared as a white suspension, was filtered to remove LiCl, and then all solvents and excess Me2SiCl2 were removed under reduced pressure to leave 11.8 g of pale yellow oil (98% yield).
