実験手順

5-Bromo-6-(3-hydroxy-3-methylazetidin-1-yl)-N-(4-(trifluoromethoxy)phenyl)nicotinamide (Stage 128.1, 89 mg, 0.2 mmol) and pyrimidin-5-ylboronic acid (50 mg, 0.4 mmol) were dissolved in DME (0.8 mL). A solution of 2 M Na2CO3 (0.300 mL, 0.6 mmol) and EtOH (120 μL) were added, the mixture was flushed with argon, Pd(PPh3)2Cl2 (17 mg, 0.02 mmol) was added and the RM was heated at 95° C. for 3 h in a pressure safe vial. After cooling at RT, the RM was treated with EtOAc and washed with brine. The organic phase was dried over Na2SO4 and evaporated to dryness under reduced pressure. The crude product was purified by flash chromatography (RediSep® Silica gel column, first EtOAc/MeOH from 0 to 10% MeOH; then second flash DCM/MeOH, from 2% to 5% MeOH) and treated with Si-Thiol (80 mg) in MeOH to afford the title compound as a white crystalline solid. HPLC (Condition 4) tR=4.74 min, UPLC-MS (Condition 7) m/z=446.3 [M+H]+; 1H-NMR (400 MHz, DMSO-d6) δ ppm 1.29 (s, 4H) 3.50-3.64 (m, 3H) 5.49 (s, 1H) 7.34 (d, J=8.60 Hz, 2H) 7.83 (d, J=8.99 Hz, 2H) 8.09 (d, J=1.56 Hz, 1H) 8.78 (d, J=1.95 Hz, 1H) 8.90 (s, 2H) 9.20 (s, 1H) 10.20 (s, 1H).
