Participants

Reaction Steps

2-methyl-4-phenylindene (synthesized substantially according to the technique reported in U.S. Pat. No. 5,329.033) (3.00 g, 0.014 moles) in THF (10 mL) was added dropwise to a stirring solution of KH (0.601 g, 0.0150 moles) in THF (50 mL). This mixture was allowed to stir for 16 hours. The solution was then filtered and added dropwise to a solution of dimethylsilyl(t-butylamino)chloride (2.41 g, 0.0145 moles) in THF (75 mL). This mixture was allowed to stir for 16 hours. After the reaction period the volatiles were removed and the residue extracted and filtered using hexane. Removal of the volatiles resulted in the isolation of the desired product as a light yellow oil (4.00 g, 82.0 percent).
