실험 절차
N-(4-Chlorophenyl)benzene-1,2-diamine (11.2 g) was added to diethyl oxalate (50 ml) and the mixture heated under reflux for 2 hours. The mixture was cooled and ethanol (40 ml) was added. The precipitated solid was filtered off and recrystallised from ethanol giving the title compound (11.2 g) mp>300° C.
