Procedure
To the 2,6,7-trichloroquinoxaline was added anhydrous EtOH (500 ml) to give a brown solution. 5.0 g (156 mmol) anhydrous hydrazine were added dropwise under N2, turning the solution red immediately. The solution was heated at reflux for 1 hour, cooled and the resulting solid was collected. Recrystallization from 1500 ml 95% EtOH yielded 13.0 g of 2-hydrazino-6,7 dichloroquinoxaline
