98416-72-9, 6-Bromo-2-chloro-3-methylquinoxaline is a quinoxaline compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated,98416-72-9
General procedure: Aminophenol (0.01 mol) was dissolved in a mixture of acetonitrile(50 mL) and DMF (5 mL) containing anhydrous potassium carbonate(2.0 g). The mixture was refluxed for 1 h, then (5, 0.01 mol)was added and the mixture was further refluxed for 6 h (monitoredby TLC). After completion of the reaction, the mixture was filteredand the excess of acetonitrile was evaporated under reduced pressureand crystallized from ethanol to give the correspondingcompounds. 4.12.1 2-[6(7)-Bromo-2-methylquinoxalin-3-yloxy]aniline (12a) The compound 12a was obtained from the reaction of o-aminophenol. Yield: 64%; (orange powder): mp 119-121 C; IR (KBr) numax in cm-1: 3412, 3325 (NH2), 2921, 2825 (aliphatic C-H), 1603 (C=N); 1H NMR (DMSO-d6, 500 MHz): delta 2.75 (s, 3H, CH3), 4.45 (br s, 2H, NH2; exchangeable with D2O), 6.83-7.73 (m, 7H, Ar-H); 13C NMR (DMSO-d6, 125 MHz): delta 20.68 (CH3), 122.60-138.01 (12Ar-C), 143.94, 149.65 (2C=N); MS (m/z), 314 (M+-CH3; 100%), 329 (M+; 35%), 330 (M++1; 13%), 331 (M++2; 34%). Anal. Calcd for C15H12BrN3O (230.18): C, 54.56; H, 3.66; N, 12.73. Found: C, 54.78; H, 3.91; N, 12.63.
As the paragraph descriping shows that 98416-72-9 is playing an increasingly important role.
