Reaktionsschritte

2,6,7-Trichloroquinoxaline was reacted with 4-(N-methylamino)phenol sulfate, following essentially the same procedure as that described in Example 1 Part (a), to give 4-[N-methyl-N-(6,7-dichloro-2-quinoxalinyl)amino]phenol. Proton magnetic resonance spectrum (d6 -acetone; δ in ppm): 8.25 (1H, s, quinoxaline hetero-ring proton); 8.0 (1H, s, quinoxaline benzo-ring proton); 7.9 (1H, s, quinoxaline benzo-ring proton); 7.15 (4H, m, phenoxy protons; 3.55 (3H, s, N-CH3).
