YieldReaction ConditionsOperation in experiment
19% In N,N-dimethyl-formamide; EXAMPLE 1 Preparation of 4-N',N'-dimethylamino-N-(6,7-dichloro-2-quinoxalinyl)benzenesulfonamide A suspension of sodium hydride (60%, 160 mg, 4.0 mmol) in N,N-dimethylformamide (10 ml) under a nitrogen atmosphere at room temperature was treated with <strong>[6162-21-6]p-dimethylaminobenzenesulfonamide</strong> (300 mg, 1.5 mmol), and after stirring one hour, solid 2,6,7-trichloroquinoxaline (308 mg, 1.33 mmol) was added. After five hours, additional 2,6,7-trichloroquinoxaline (45 mg, 0.20 mmol) was added and stirring continued overnight. The reaction mixture was carefully poured into excess pH 4.0 buffer and extracted with ethyl acetate (3X). The combined extract was washed with water, brine and dried over sodium sulfate. Filtration and evaporation yielded a solid which was purified by silica gel flash chromatography (EtOAc/hexanes) to yield the title product (100 mg, 19%) as a solid. Analysis of the title compound gave the following results: 1 H NMR (300 MHz, d6 -DMSO)delta2.94(s, 6H, CH3), 6.74, (d, 2H, J=9.1 Hz, Ar-H), 7.87 d, 2H, J=9.0 Hz, Ar-H), 8.07 (s, 1H, Ar-H), 8.20 (s, 1H, Ar-H), 8.52 (s, 1H, Ar-H), 11.82 (s, 1H, exchanges with D2 O, NH); IR(KBr) 3114, 3057, 1601, 1383, 1316 and 1154 cm-1; UV(EtOH)lambdamax(epsilon) 216.0(41035), 254.4(29214), 283.2(23127) and 350.2 (8436) nm; FDMS(DMSO) m/e=396, 398, 400 (M+).

YieldReaction ConditionsOperation in experiment
(c) 2,6,7-Trichloroquinoxaline was reacted with <strong>[51-72-9]4-(N-methylamino)phenol sulfate</strong>, 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; delta 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).
