실험 절차
A solution was prepared from 0.9 g. of 4,5-di-iodo-o-phenylenediamine and 25 ml. of ethanol. Five grams of diethyl ketomalonate were added and the resulting mixture was heated to refluxing temperature with stirring overnight. The reaction mixture was then cooled. Ethyl 6,7-di-iodo-3,4-dihydro-3-oxo-2-quinoxaline carboxylate formed in the above reaction precipitated and was collected by filtration; yield=0.8 g.; mp=275°-276° C.
