実験手順

To a mixture of 2-(2′,3-difluoro-2,4′-bipyridin-5-yl)acetic acid 205-6 (25 mg, 0.1 mmol), 5-(pyridazin-3-yl)pyridin-2-amine 145-3 (17 mg, 0.1 mmol), o-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (HATU, 38 mg, 0.1 mmol) were added DMF (0.5 mL) and diispropylethyl amine (DIEA, 0.05 mL, 0.3 mmol) and the mixture was stirred at room temperature overnight. The crude DMF solution was directly purified by reverse phase HPLC to give 2-(2′,3-difluoro-2,4′-bipyridin-5-yl)-N-(5-(pyridazin-3-yl)pyridin-2-yl)acetamide 210 as white solid. MS m/z 405.1 (M+1); 1H NMR 400 MHz (DMSO-d6) δ 11.18 (s, 1H), 9.23 (d, 1H), 9.14 (d, 1H), 8.61 (m, 1H), 8.56 (dd, 1H), 8.41 (d, 1H), 8.29 (dd, 1H), 8.23 (d, 1H), 7.95 (dd, 1H), 7.91-7.86 (m, 1H), 7.81 (dd, 1H), 7.65 (s, 1H), 4.02 (s, 2H).
