Procedure

48.5 parts of 1-bromoethylcarbamic acid bromide are dissolved in 100 parts by volume of α-chloronaphthalene and a solution of 16 parts of vinyl isocyanate in 20 parts by volume of 1-chloronaphthalene is added to the above mixture in the course of 0.4 hour at 2° C. The mixture is then kept at 24° C. for 2 hours. 3.6 parts (11% of theory) of vinyl isocyanate and 58.5 parts (88% of theory) of 1-bromoethyl isocyanate (determined by gas chromatography) are obtained.
