Procedure

A 2-MeTHF (253 mL)/water (56 mL) 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, (24.3 g, 58.3 mmol), methyl (R)-methyl 3-((2-chloro-5-fluoropyrimidin-4-yl)amino)-4,4-dimethylpentanoate, 6a, (14.1 g, 48.6 mmol) and K3PO4 (30.9 g, 146 mmol) was purged with nitrogen for 0.75 h. XPhos (2.8 g, 5.8 mmol) and Pd2(dba)3 (1.1 g, 1.2 mmol) were added and the reaction mixture was stirred at 115° C. in a sealed tube for 2 h. The reaction mixture was cooled and the aqueous phase was removed. The organic phase was filtered through a pad of Celite and the mixture was concentrated to dryness. The residue was purified on silica gel (EA/Hex) to provide the desired product, 8a, (23.2 g): LCMS Gradient 10-90%, 0.1% formic acid, 5 min, C18/ACN, RT=2.18 minutes (M+H) 245.28.
