反応手順

A mixture of 4-(4-bromo-2-fluorophenylamino)-1-methyl-6-oxo-1,6-dihydropyridine-3-carboxylic acid (0.069 g, 0.202 mmol), EDCI (0.12 g, 0.61 mmol), and HOBt (0.082 g, 0.61 mmol) in DMF (5 mL) was stirred for 30 minutes. NH4Cl (0.033 g, 0.61 mmol) was added followed by Et3N (0.085 mL, 0.61 mmol). After 1 hour, the reaction mixture was diluted with EtOAc and washed with saturated NH4Cl solution, saturated NaHCO3 solution and brine. The organic layer was dried (MgSO4) and concentrated to yield 52 mg (76%) clean desired product as an off-white solid. MS APCI (+) m/z 340, 342 (M+, Br pattern) detected; 1H NMR (400 MHz, DMSO-d6) δ 10.39 (s, 1H), 8.34 (s, 1H), 7.67 (dd, 1H), 7.43 (m, 2H), 3.36 (s, 3H).
