Reaction Steps

A solution of 0.93 mL (0.0089 mol) of tert-butylamine in 30 mL of ether was treated dropwise with 5.55 mL (0.0089 mol) of 1.6M BuLi in hexane at −30° C. The reaction mixture was stirred at r.t. for 3 h and the resulting suspension was treated with a solution of 2.47 g (0.0088 mol) of chloro(dimethyl)(2-methyl-8H-indeno[2,1-b]thiophen-8-yl)silane in 10 mL of ether at −70° C. The resulting suspension was allowed to warm to r.t. and was stirred overnight. The solution was separated from LiCl and evaporated. The residue was treated with 60 mL hexane, the solution was isolated and evaporated. Yield 1.98 g (71%) of crude product as red oil.
