실험 절차
A solution of 6-amino-1,2-dihydro-2,2-dimethyl-3-(4H)-quinoxalinone (250 mg, 1.31 mmol) in glacial acetic acid (4 ml) is cooled using a water bath. Bromine (210 mg, 1.31 mmol) in acetic acid (0.25 ml) is added dropwise over a 5 minute period. The mixture is stirred at room temperature for 4 hours and the resulting precipitate is collected by vacuum filtration. The title compound is obtained in pure form after drying in vacuo.
