실험 절차

To a solution of 2-methyl-8-nitroquinoline (1.88 g, 10 mmol) and 1,1,1-trimethylhydrazinium iodide (3.03 g, 15 mmol) in anhydrous dimethyl sulfoxide (20 mL) was added potassium tert-butoxide as a solid (3.36 g, 30 mmol). The mixture was stirred at room temperature for 1 h. The mixture was then poured into saturated aqueous ammonium chloride, and extracted with EtOAc. The organic layer was concentrated and purified by column chromatography to give 2-methyl-8-nitroquinolin-7-amine as a yellow solid (300 mg).
