실험 절차
0.5 g of anhydrous iron-III chloride is added to 203 g of 2,6-diisopropyl-phenyl isocyanate and 162 g of bromine are added dropwise at 20° C. The mixture is then slowly warmed to 120° C. until the evolution of gas has ceased. 3.0 g of anhydrous sodium sulfate are then added and the mixture is fractionated in vacuo.
