Yield:141215-31-8 58%
Reaction Conditions:
in ethanol;water at 80; for 3 h;
Steps:
12 Preparation of 4,9-dibromo- [1,2,5] thiadiazolo [3,4-g] quinoxaline (compound l-3)
Condenser equipped with a 250 mL round bottom flask on a 4,7-dibromobenzo [c] [1,2,5] thiadiazole-5 ,6-diamine (compound l-2) 1.5 g After the insert, 38 mL ethanol, and both the injection dissolved. Then, glyoxal (40% aq.) And then injecting a 0.825 g slowly, stirred for 3 hours at 80 °. After 3 hours, there is a yellow solid product is produced by filter through methanol which the 4,9-dibromo-[1,2,5] thiadiazolo [3,4-g] quinoxaline, to obtain the (compound l-3). (Yield: 58%)
