실험 절차

A mixture of 2-(2′-fluoro-2,4′-bipyridin-5-yl)acetic acid 208-3 (42 mg, 0.18 mmol), 5-(pyrazin-2-yl)pyridin-2-amine 86-3 (31 mg, 0.18 mmol), 1,3-dicyclohexylcarbodiimide (45 mg, 0.22 mmol) and 4-(dimethylamino)pyridine (4 mg, 0.036 mmol) in DMF (0.9 mL) was stirred at room temperature for 10 hours. The crude product was filtered and the filtrate was purified by reverse phase HPLC to give 2-(2′-fluoro-2,4′-bipyridin-5-yl)-N-(5-(pyrazin-2-yl)pyridin-2-yl)acetamide 208 as white solid. MS m/z 387.1 (M+1); 1H NMR 400 MHz (DMSO-d6) δ 11.14 (s, 1H), 9.31 (d, 1H), 9.11 (d, 1H), 8.73-8.71 (m, 2H), 8.62 (d, 1H), 8.52 (dd, 1H), 8.36 (d, 1H), 8.23-8.17 (m, 2H), 8.06-8.02 (m, 1H), 7.95 (dd, 1H), 7.82 (s, 1H), 7.64 (s, 1H), 3.94 (s, 2H).
