Reaction Steps

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, (0.158 g, 0.380 mmol), (S)-(1-(2-((2-chloro-5-fluoropyrimidin-4-yl)amino)-3,3-dimethylbutyl)-1H-1,2,3-triazol-4-yl)methanol, 217a, (0.100 g, 0.304 mmol) and K3PO4 (0.520 g, 2.440 mmol) in 2-methyl THF (8 mL) and water (2 mL) was degassed under a stream of nitrogen for 30 minutes. X-Phos (0.008 g, 0.018 mmol) and Pd2(dba)3 (0.006 g, 0.006 mmol) were added and the reaction mixture was heated at 115° C. in a pressure vial for 4 hours. The reaction mixture was cooled to room temperature and filtered. The filtrate was concentrated in vacuo. The residue was dissolved in EtOAc (50 mL) and washed with water. The organic layer was dried (MgSO4), filtered concentrated in vacuo. The crude residue was purified via silica gel chromatography (0-70% EtOAc/Hexanes gradient) to afford 120 mg of the desired product as a white foamy solid: 1H NMR (400 MHz, CDCl3) δ 8.37 (s, 1H), 8.33 (s, 1H), 8.21 (s, 1H), 8.03 (d, J=8.4 Hz, 2H), 7.90 (d, J=3.0 Hz, 1H), 5.37 (m, 1H), 4.92 ? 4.83 (m, 1H), 4.78-4.69 (m, 2H), 4.44 (dd, J=13.9, 11.3 Hz, 1H), 2.32 (s, 3H), 1.11 (s, 9H); LCMS Gradient 60-98%, 0.1% formic acid, 7 minutes, C18/ACN, Retention Time=1.29 minutes (M+H) 583.33
