Versuchsvorschrift

A mixture consisting of 18.1 g of α,α-dimethylbenzyl-isocyanate and 14.2 g of 2-chlorobenzylamine was allowed to stand for 2 hours at room temperature. The white deposit formed was then filtered off. Washing with n-hexane and recrystallization from ethanol gave 28.5 g of colorless crystal product, m.p. 165°-166° C.
