実験手順

A mixture of 2-(2′,3-difluoro-2,4′-bipyridin-5-yl)acetic acid 205-6 (50 mg, 0.2 mmol), 5-(pyrazin-2-yl)pyridin-2-amine 86-3 (34 mg, 0.2 mmol), 1,3-dicyclohexylcarbodiimide (50 mg, 0.24 mmol) and 4-(dimethylamino)pyridine (4 mg, 0.04 mmol) in DMF (0.9 mL) was stirred at room temperature for 10 hours. The crude product was filtered and the filtrate was subjected directly for reverse phase HPLC to give 2-(2′,3-difluoro-2,4′-bipyridin-5-yl)-N-(5-(pyrazin-2-yl)pyridin-2-yl)acetamide 205 as white solid. MS m/z 405.2 (M+1); 1H NMR 400 MHz (DMSO-d6) δ 11.16 (s, 1H), 9.31 (d, 1H), 9.12 (d, 1H), 8.72 (dd, 1H), 8.63 (d, 1H), 8.61-8.60 (m, 1H), 8.52 (dd, 1H), 8.41 (d, 1H), 8.21 (d, 1H), 7.94 (dd, 1H), 7.88 (dd, 1H), 7.64 (s, 1H), 4.01 (s, 2H).
