Versuchsvorschrift

A mixture of 4.61 g (25 mmoles) of methyl N-(4-chlorophenyl)-carbamate, 4.07 g (25 mmoles) of 3,4-dichloroaniline, 100 ml of toluene and 4.7 g (25 mmoles) of N,N-dimethyl-dodecylamine is reacted for 20 hours as described in Example 8, and then the mixture is allowed to cool. 4.60 g (58.4%) of N-(4-chlorophenyl)-N'-(3,4-dichlorophenyl)-urea separate from the mixture as a crystalline substance.
