실험 절차

A mixture of 5-fluoro-1-(p-tolylsulfonyl)-3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyrrolo[2,3-b]pyridine, 7a, (11.09 g, 26.64 mmol), (S)-2-(2-chloro-5-fluoropyrimidin-4-yl)amino)-3,3-dimethylbutan-1-ol, 14a, (6.00 g, 24.22 mmol) and K3PO4 (15.42 g, 72.66 mmol) in 2-methyl THF (90 mL) and water (12.00 mL) was purged with nitrogen for 30 minutes. X-Phos (0.92 g, 1.94 mmol) and Pd2(dba)3 (0.44 g, 0.48 mmol) were added and the reaction mixture was heated at 120° C. in a pressure vial for 2 hr. The reaction mixture was cooled to room temperature, filtered and concentrated in vacuo. The residue was dissolved in EtOAc (100 mL) and washed with water. The organic layer was dried (MgSO4), filtered and concentrated in vacuo. The crude product was purified by silica gel chromatography (0-40% EtOAc/Hexanes gradient) to afford 10 g of the desired product as a foamy solid: 1H NMR (400 MHz, CDCl3) δ 8.54-8.40 (m, 2H), 8.22 (s, 1H), 8.09-8.00 (m, 3H), 7.29-7.16 (m, 2H), 5.15 (m, 1H), 4.32-4.14 (m, 1H), 3.98 (m, 1H), 3.70 (m, 1H), 2.30 (s, 3H), 1.01 (m, 9H); LC/MS (60-90% ACN/water 5 min with 0.9% FA, C4) m/z 502.43 (M+H) RT=1.52 min.
