(5,6-Dimethoxy-1H-inden-1-yl)lithium (2.5 g, 13.73 mmol) slurried in 40 mL of THF was added to a solution of N-(tert-butyl)-N-(1-chloro-1,1-dimethylsilyl)amine (3.185 g, 19.22 mmol) in 100 mL of THF over a 25 min period. After stirring for 18 h, the volatile components were removed under reduced pressure. The residue solution was extracted with hexane (40 mL). After filtration the volatile components were removed in under vacuum to give 3.95 g, 94 percent yield of the desired product as a light yellow oil.
