Procedure

A solution of 5-fluoro-1-(p-tolylsulfonyl)-3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyrrolo[2,3-b]pyridine, 7a, (0.76 g, 1.83 mmol), (S)-tert-Butyl 2-(2-(2-chloro-5-fluoropyrimidin-4-ylamino)-3,3-dimethylbutyl-sulfonyl)ethanoate, 169a, (0.75 g, 1.83 mmol) and K3PO4 (0.93 g, 4.39 mmol) in 2-methyl THF (10 mL) and water (2 mL) was degassed under a stream of nitrogen for 30 minutes. X-Phos (0.06 g, 0.12 mmol) and Pd2(dba)3 (0.03 g, 0.03 mmol) were added and the reaction mixture was heated at 115° C. in a pressure vial for 2.5 hours. The reaction mixture was cooled to room temperature, filtered and concentrated in vacuo. The residue was dissolved in EtOAc (50 mL) and washed with water. The organic layer was dried (MgSO4), filtered and concentrated in vacuo. The crude product was purified via silica gel chromatography (0-60% EtOAc/Hexanes gradient) to afford 1.0 g of the desired product as a foamy solid: LCMS Gradient 60-98% ACN/water, 0.9% formic acid, 7 minutes, C4, Retention Time=2.39 minutes (M+H) 564.34.
