Procedure

To a mixture of 2-neopentylindene (0.81 g, 4.3 mmol) in 30 mL of hexanes were added 2.9 mL of butyl lithium (1.6 M hexane; 4.7 mmol). The mixture was stirred for one hour, diluted with 20 mL of THF and to this added N-(1,1-dimethylethyl)dimethylsilanamine chloride (1.84 g, 11.2 mmol) in 10 mL of THF. After stirring overnight, the volatiles were removed in vacuo, the residue extracted with hexane, filtered and the volatiles removed in vacuo to give 1.4 g (102 percent) of a yellow oil.
