PROCEDURE
实验过程
A solution of (S)-2-chloro-N-(3,3-dimethyl-1-(methylsulfonyl)butan-2-yl)-5-fluoropyrimidin-4-amine, 79a, (0.15 g, 0.48 mmol), 5-fluoro-1-(p-tolylsulfonyl)-3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyrrolo[2,3-b]pyridine (0.24 g, 0.58 mmol), and K3PO4 (0.25 g, 1.16 mmol) in 2-methyl THF (5 mL) and water (1 mL) was purged with nitrogen for 30 minutes. X-Phos (0.015 g, 0.031 mmol) and Pd2(dba)3 (0.007 g, 0.008 mmol) were added and the reaction mixture was heated at 120° C. in a pressure vial for 2 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 residue was purified by silica gel chromatography (0-40% EtOAc/Hexanes gradient) to afford 210 mg of the desired product as a white foamy solid: 1H NMR (400 MHz, CDCl3) δ 8.54-8.43 (m, 2H), 8.24 (d, J=1.3 Hz, 1H), 8.09 (s, 1H), 8.03 (d, J=8.2 Hz, 2H), 7.23 (s, 1H), 4.99 (dt, J=20.3, 10.1 Hz, 2H), 3.37 (d, J=14.4 Hz, 1H), 3.07 (dt, J=31.3, 15.7 Hz, 1H), 2.83 (s, 3H), 2.33 (d, J=19.0 Hz, 3H), 0.98 (d, J=20.7 Hz, 9H); LC/MS (10-90% ACN/water 5 min with 0.9% FA, C4) m/z 564.20 (M+H) RT=3.70 minutes.
