A solution of N-((1R,3S)-3-(2-chloro-5-fluoropyrimidin-4-ylamino)cyclohexyl)-pyrrolidine-1-carboxamide, 67e, (6.8 g, 20.0 mmol), 5-fluoro-1-(p-tolylsulfonyl)-3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyrrolo[2,3-b]pyridine, 44a, (12.5 g, 30.0 mmol) and K3PO4 (17.0 g, 80.0 mmol) in 2-methyl THF (180 mL) and water (20 mL) was degassed under nitrogen for 30 min. To the mixture was added dicyclohexyl-[2-(2,4,6-triisopropylphenyl)phenyl]phosphane (XPhos) (1.1 g, 2.4 mmol) and Pd2(dba)3 (0.5 g, 0.5 mmol). The reaction mixture was heated in a pressure bottle at 125° C. for 2.5 hr. The reaction mixture was filtered through celite, the solvent was removed under reduced pressure. The resulting residue was purified by silica gel chromatography (8% MeOH/CH2Cl2) to afford 11.5 g of the desired product.
