Reaktionsschritte
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: 1H NMR (300 MHz, CDCl3) δ 8.54 (s, 1H), 8.49 (dd, J=9.0, 2.8 Hz, 1H), 8.32 (d, J=2.1 Hz, 1H), 8.13 (d, J=8.3 Hz, 2H), 8.07 (d, J=3.2 Hz, 1H), 7.30 (d, J=8.5 Hz, 2H), 4.98 (d, J=6.3 Hz, 1H), 4.37-4.16 (m, 1H), 4.08 (d, J=7.3 Hz, 1H), 3.99-3.80 (m, 1H), 3.33 (t, J=6.5 Hz, 4H), 2.52 (d, J=11.6 Hz, 1H), 2.39 (s, 3H), 2.29 (d, J==11.3 Hz, 1H), 2.12 (d, J=11.1 Hz, 1H), 1.99-1.81 (m, 5H), 1.70-1.55 (m, 1H), 1.22-1.08 (m, 2H).
