98416-72-9, 4.8 6-Bromo-2-hydrazinyl-3-methylquinoxaline (8) To a solution of compound (5, 0.01 mol) in absolute ethanol (50 mL), hydrazine hydrate 90% (0.015 mol) was added and the reaction mixture was refluxed for 10 h (monitored by TLC). After completion of the reaction, the reaction mixture was filtered, dried and crystallized from methanol to give the product. Yield: 86%; (red-brown powder): mp 129-131 C; IR (KBr) numax in cm-1: 3303, 3253, 3144 (NH2, NH), 2920, 2870 (aliphatic C-H), 1596 (C=N); 1H NMR (DMSO-d6, 500 MHz): delta 2.74 (s, 3H, CH3), 4.51 (s, br s, 2H, NH2; exchangeable with D2O), 7.93-8.27 (m, 3H, Ar-H), 9.02 (s, br s, 1H, NH; exchangeable with D2O); 13C NMR (DMSO-d6, 125 MHz): delta 123.33-140.76 (6Ar-C), 147.84, 148.39 (2C=N); MS (m/z), 237 (M+-CH3; 100%), 252 (M+; 40%), 253 (M++1; 10%), 254 (M++2; 38%). Anal. Calcd for C9H9BrN3 (253.10): C, 42.71; H, 3.58; N, 22.14. Found: C, 42.97; H, 3.44; N, 22.32.
