Procedure

A mixture of crude Intermediate N-(2,4-difluoro-3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)propane-1-sulfonamide (854 mg), Intermediate (S)-methyl 1-(4-(3-iodo-1-isopropyl-1H-pyrazol-4-yl)pyrimidin-2-ylamino)propan-2-ylcarbamate (350 mg, 90% pure), tetrakis(triphenylphosphine)palladium(0) (90 mg), 2 M aqueous sodium carbonate solution (6 ml), toluene (50 ml), and ethanol (6 ml) was heated at 80° C. for 16 h. The cooled mixture was extracted with ethyl acetate and the combined organic extracts were washed with brine. The organic phase was dried over sodium sulfate and concentrated. The crude product was purified by silica gel chromatography (70:1 to 40:1 DCM/methanol eluant) to provide the title compound.
