Reaction Steps

To a solution of N-methyl-8-nitroquinolin-7-amine (1.6 g, 7.9 mmol) in MeOH (25 mL) was added hydrazine hydrate (2.25 g, 455 mmol) and Raney Ni (8 drops). The mixture was stirred at room temperature for 20 minutes. The catalyst was removed by filtration and the filtrate was concentrated to give N7-methylquinoline-7,8-diamine as a yellow solid (1.2 g, yield 80%). ESI MS: m/z 174 [M+H]+.
