実験手順

To a solution of 8-nitroquinolin-7-amine (1.89 g, 10 mmol) in tetrahydrofuran (THF) (10 mL) was added sodium hydride (60% wt in mineral oil, 800 mg, 20 mmol). The mixture was stirred at room temperature for 30 minutes, then iodomethane (1.42 g, 10 mmol) was added. The mixture was stirred at room temperature for 5 h. Then water (10 mL) was added. The mixture was extracted with EtOAc, and the organic layer was concentrated. The residue was purified by silica gel column chromatography (eluting with PE/EtOAc v/v 2:1) to give N-methyl-8-nitroquinolin-7-amine as a yellow solid (1.6 g, yield 79%). ESI MS: m/z 204 [M+H]+.
