Versuchsvorschrift
A solution of 54 g of 2,3-dibromopropionyl isocyanate in 100 ml of benzene is added dropwise with cooling at 20° C. to a solution of 25 g of 4-chloroaniline in 250 ml of dry benzene. After stirring for 3 hours at 20° C., the suspension is diluted with 200 ml of petroleum ether, filtered and dried. Yield: 71.0 g, m.p.: 162° - 163° C.
