실험 절차
14.0 g of 4-nitroaniline are dissolved in 200 ml of anhydrous acetonitrile, and 26.0 g of 2,3-dibromopropionyl isocyanate are added dropwise with cooling at 5° to 10° C. After stirring for 3 hours at 20° C., the solid precipitated is filtered off and dried. Yield: 35.0 g m.p.: 205° - 206° C. (decomp.).
