Participants

Reaction Steps

A mixture of 2-(2′-methyl-2,4′-bipyridin-4-yl)acetic acid 238-3 (46 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 to remove the insoluble and the filtrate was submitted directly for reverse phase HPLC purification to give 2-(2′-methyl-2,4′-bipyridin-4-yl)-N-(5-(pyrazin-2-yl)pyridin-2-yl)acetamide 238 as white solid. MS m/z 383.1 (M+1); 1H NMR 400 MHz (DMSO-d6) δ 11.14 (s, 1H), 9.30 (d, 1H), 9.11 (dd, 1H), 8.73-8.71 (m, 1H), 8.67 (d, 1H), 8.62 (d, 1H), 8.56 (d, 1H), 8.52 (dd, 1H), 8.21 (d, 1H), 8.09 (s, 1H), 7.93 (s, 1H), 7.84 (dd, 1H), 7.45 (dd, 1H), 3.95 (s, 2H), 2.56 (s, 3H).
