Procedure

2,3-Dichloroquinoxaline (prepared according to the method of H M Woodburn, J. Org. Chem., 1958, 23, 262) 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-(3-chloro-2-quinoxalinyl)amino]phenol. Proton magnetic resonance spectrum (d6 -acetone; δ in ppm): 7.5-8.1 (4H, m, quinoxaline protons); 7.1 (4H, m, phenoxy protons); 3.5 (3H, s, N-CH3).
