Reaction Steps
26.0 g of 2,3-dibromopropionyl isocyanate in 100 ml of toluene are added dropwise at 5 to 10° C to a solution of 14.5 g of 1-aminonaphthalene in 200 ml of dry benzene. After stirring for 2 hours at 20° C., the reaction product is diluted with petroleum ether, filtered and dried. Yield: 35.0 g, m.p: 194° - 195° C. (decomp.).
