실험 절차

5-Bromo-6-(3-(2-hydroxypropan-2-yl)pyrrolidin-1-yl)-N-(4-(trifluoromethoxy)phenyl)nicotinamide (Stage 113.1, 98 mg, 0.2 mmol) and pyrimidin-5-ylboronic acid (49.6 mg, 0.4 mmol) were dissolved in DME (0.8 mL) and EtOH (0.12 mL). A solution of 2 M NaHCO3 (0.3 mL, 0.6 mmol) was added, the RM was flushed with argon, then Pd(PPh3)2Cl2 (14.0 mg, 0.02 mmol) was added. The RM was stirred under argon at 95° C. for 2 h in a sealed pressure safe tube. After cooling at RT, the RM was dissolved in EtOAc, washed with brine, dried over Na2SO4 and evaporated to dryness under reduced pressure. The crude product was purified by flash chromatography (RediSep® Silica gel column, DCM/MeOH from 2% to 5% MeOH) and treated with Si-Thiol (80 mg) in MeOH to afford the title compound as a white solid. HPLC (Condition 4) tR=4.94 min, UPLC-MS (Condition 3) tR=1.01 min, m/z=532.3 [M+H]+; 1H-NMR (400 MHz, DMSO-d6) δ ppm 0.90-1.08 (m, 6H) 1.58-1.83 (m, 2H) 1.99-2.15 (m, 1H) 3.05-3.23 (m, 3H) 3.25-3.35 (m, 1H) 4.29 (s, 1H) 7.33 (d, J=8.60 Hz, 2H) 7.75-7.87 (m, 2H) 8.07 (d, J=2.35 Hz, 1H) 8.77 (d, J=2.35 Hz, 1H) 8.87 (s, 2H) 9.17 (s, 1H) 10.14 (s, 1H).
