実験手順

Into 20 ml of methanol was dissolved 726 mg of 2-methoxy-6-nitroquinoxaline, and then 1.0 g of iron powder and a saturated ammonium chloride aqueous solution were added thereto, followed by heating under refluxing overnight. Insoluble matter was separated by filtration using celite and then the solvent was removed by evaporation. A sodium bicarbonate aqueous solution was added to the residue, followed by extraction with ethyl acetate. After the organic layer was dried over anhydrous magnesium sulfate, the solvent was removed by evaporation and the resulting residue was purified by silica gel column chromatography to obtain 770 mg of the title compound from chloroform-methanol (100:1, v/v).
