실험 절차

5-Amino-6-nitroquinoxaline was synthesized by reaction of 6-nitroquinoxaline with hydroxylamine in an alkaline medium in accordance with J. Chem. Soc., Perkin I, 1975, 1229. The product was reacted With sodium borohydride as in Example 1). The 1,2,3,4-tetrahydro-5-amino-6-nitroquinoxaline obtained in the form of brown crystals in a yield of 11.5% of the theoretical had a melting point of 213° C.
