실험 절차

To a solution of N-methyl-5-nitroquinoxaline-6-amine (1.3 g, 6.4 mmol) in MeOH (100 mL) was added hydrazine hydrate (1.27 g, 25.5 mmol) and Raney Ni (0.2 g). The mixture was stirred at room temperature for 1 h. The mixture was then filtered, and the filtrate was concentrated under reduce pressure to give N6-methylquinoxaline-5,6-diamine as a black solid (1.14 g, yield 100%). ESI MS: m/z 175.1 [M+H]+.
