Following a method similar to 3-morpholin-4-yl-1-triisopropylsilanyl-1H-indole using 3-bromo-1-triisopropylsilanyl-1H-indole (0.70 g, 1.99 mmol), piperidine (0.26 g, 3.04 mmol), 2-dicyclohexylphosphino-2′-(N,N-dimethylamino)biphenyl (0.02 g, 0.05 mmol), tris(dibenzylideneacetone)dipalladium(0) chloroform adduct (0.05 g, 0.05 mmol) and 1N solution of lithium bis(trimethylsilyl)amide in THF (2.40 mL) to prepare the title compound. Purify by flash chromatography using 0 to 40% of EtOAc in hexanes to give the title compound (0.20 g, 29%): MS (ES) 357.1 (M+1)+.
