実験手順

A mixture of 2-(4-(2-(difluoromethyl)pyridin-4-yl)phenyl)acetic acid 203-5 (70 mg, 0.27 mmol), 5-(pyrazin-2-yl)pyridin-2-amine (55 mg, 0.32 mmol), N,N-diisopropylethylamine (139 μL, 0.80 mmol) and O-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluroniumhexafluorophosphate (152 mg, 0.40 mmol) in DMF (2 mL) 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-(4-(2-(difluoromethyl)pyridin-4-yl)phenyl)-N-(5-(pyrazin-2-yl)pyridin-2-yl)acetamide 203. MS m/z 418.2 (M+1); 1H NMR 400 MHz (CDCl3) δ 8.99 (d, 1H), 8.90 (dd, 1H), 8.70 (d, 1H), 8.63 (dd, 1H), 8.53 (d, 1H), 8.40-8.33 (m, 2H), 8.30 (s, 1H), 7.84 (s, 1H), 7.70-7.68 (m, 2H), 7.62-7.60 (m, 1H), 7.50-7.49 (m, 2H), 6.70 (t, 1H), 3.87 (s, 2H).
