Versuchsvorschrift
To the solution of 3-bromo-4-chloro-1-(phenylsulfonyl)-1H-pyrrolo[2,3-b]pyridine in 1,3-dimethyl-2-imidazolidinone was added Zn(CN)2 and tetrakis(triphenylphosphine)palladium(0) at ambient temperature. This was stirred at 140° C. for 1.5 hours. The reaction was cooled and was added water, extracted with EtOAc. The organic layer was washed with brine and was dried over MgSO4 and evaporated. Resultings were purified by silica gel column chromatography to afford 4-chloro-1-(phenylsulfonyl)-1H-pyrrolo[2,3-b]pyridine-3-carbonitrile as white powder.
