実験手順

A mixture of 4-(5-(carboxymethyl)-3-methylpyridin-2-yl)-2-methylpyridine 1-oxide 156-6 from Step 4 (0.41 mmol), 5-(pyrazin-2-yl)pyridin-2-amine 86-3 (141 mg, 0.82 mmol), 1,3-dicyclohexylcarbodiimide (188 mg, 0.90 mmol) and 4-(dimethylamino)pyridine (16 mg, 0.16 mmol) in DMF (2 mL) was stirred at room temperature for 10 hours. The crude product was filtered to remove the insoluble and the filtrate was purified by reverse phase HPLC to give 2-methyl-4-(3-methyl-5-(2-oxo-2-(5-(pyrazin-2-yl)pyridin-2-ylamino)ethyl)pyridin-2-yl)pyridine 1-oxide 156 as white solid. MS m/z 413.2 (M+1); 1H NMR 400 MHz (DMSO-d6) δ 11.12 (s, 1H), 9.31 (d, 1H), 9.11 (d, 1H), 8.72 (m, 1H), 8.62 (d, 1H), 8.52 (dd, 1H), 8.48 (d, 1H), 8.31 (d, 1H), 8.21 (d, 1H), 7.73 (m, 2H), 7.52 (dd, 1H), 3.86 (s, 2H), 2.41 (s, 3H), 2.40 (s, 3H).
