108229-82-9, 6-Bromo-2,3-dichloroquinoxaline is a quinoxaline compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
To a solution of 1 (2.78 g, 0.01 mol) in DMF(50 mL), 2-aminopyridine (0.94 g, 0.01 mol) was added. The reaction mixture was refluxed for 17 h. After completion of the reaction, the reaction mixture was poured onto crushed ice with stirring. Then, the precipitate that formed was filtered, washed with water, dried and crystallized from petroleum ether(80-100C) to give the product. Yield: 40%; (yellow-brown powder): m.p.157-159 O C; IR (KBr, cm -1 ): 1610 (C=N). 1 H NMR(DMSO-d 6 , delta , ppm): 7.27-7.77 (m, 7H, Ar-H). 13 CNMR (DMSO-d 6 , delta , ppm): 121.79-141.44 (10Ar-C),151.27, 151.56, 151.91 (3C=N).
