Procedure

To a solution of 2-iodo-4-[1-methyl-3-(4-nitrophenyl)-1H-pyrazol-4-yl]-1-(phenylsulfonyl)-1H-pyrrolo[2,3-b]pyridine (0.321 mmol) and 1,1-dimethylethyl 4-[5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-2-pyrimidinyl]-1-piperazinecarboxylate (0.353 mmol) in 1,4-dioxane (3 ml) was added saturated NaHCO3(aq) (0.85 ml). After degassing with argon for 10 minutes, dichlorobis(triphenylphosphine) palladium(II) (0.0161 mmol) was added and the resulting mixture was heated at 95° C. overnight. Upon cooling, the reaction was concentrated and partitioned between EtOAc and H2O. The organic layer was washed with brine, dried (MgSO4), filtered and concentrated to yield the title compound as a yellow oil (quant.). ESMS [M+H]+: 722.2.
