Procedure

3-(4-Bromo-benzyl)-1-triisopropylsilanyl-1H-pyrrolo[2,3-b]pyridine (111, 330.0 mg, 0.74 mmol), benzylamine (160 mg, 1.5 mmol), 2-[di(tert-butyl)phosphino]-1,1′-biphenyl (15.0 mg, 0.05 mmol), tris(dibenzylideneacetone)dipalladium(0) (15.0 mg, 0.016 mmol), potassium tert-butoxide (100 mg, 0.89 mmol) and toluene (10.0 mL) were combined under an atmosphere of nitrogen. The reaction mixture was refluxed overnight, then poured into water and extracted with ethyl acetate. The organic layer was washed with brine, dried over sodium sulfate, concentrated and purified with silica gel chromatography to give the compound (112, 260 mg, 75%).
