Versuchsvorschrift
Piperazine (0.86 g, 10 mmol) was added to a stirred suspension of 6,7-difluoro-2,3-dichloroquinoxaline*(1.18 g, 5 mmol) in EtOH (50 mL) at room temperature. The mixture was heated at 75° C. for 17 h, allowed to cool and filtered to give the product as a pale yellow solid: yield 0.40 g (28%); mp 294-297° C. (dec). MS m/z 285/287 (M+H)+.
