Reaction Steps

4-Chloro-1-methyl-3-nitro-1H-pyridin-2-one was coupled to 3-bromo-4-fluorophenylamine, in the same way as in Example 1, to give 4-(3-bromo-4-fluorophenylamino)-1-methyl-3-nitro-1H-pyridin-2-one as a beige solid (2.0 g, 40%): δH (400 MHz, d6-DMSO) 3.36 (3H, s), 5.81 (1H, d, J 8), 7.33-7.37 (1H, m), 7.45 (1H, t, J 9), 7.64-7.68 (1H, m), 7.66 (1H, s), 9.73 (1H, s).
