실험 절차

2-(3-fluoro-4-(2-fluoropyridin-4-yl)phenyl)acetic acid 207-6 (50 mg, 0.20 mmol), was dissolved in DMF (2 mL), 5-(pyrazin-2-yl)pyridin-2-amine (41 mg, 0.24 mmol) and DIEA (174 uL, 1.0 mmol) were added to the solution before O-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluroniumhexafluorophosphate (114 mg, 0.30 mmol). The mixture was stirred at room temperature overnight. The solvent was removed by rotary evaporation. The crude product was purified by reverse phase HPLC to give 2-(3-fluoro-4-(2-fluoropyridin-4-yl)phenyl)-N-(5-(pyrazin-2-yl)pyridin-2-yl)acetamide 212. MS m/z 404.1 (M+1); 1H NMR 400 MHz (DMSO-d6) δ 11.10 (s, 1H), 9.31 (d, 1H), 9.11 (dd, 1H), 8.73-8.71 (m, 1H), 8.63 (d, 1H), 8.52 (dd, 1H), 8.34 (d, 1H), 8.21 (d, 1H), 7.70-7.52 (m, 2H), 7.43-7.34 (m, 3H), 3.89 (s, 2H).
