Versuchsvorschrift

A solution of 3.9 g of m-chloro-α,α-dimethylbenzyl isocyanate, prepared from the corresponding cyanide in the same way as in Synthesis Example 1, in 10 ml of n-hexane was added to 4 g of N-methyl-N-pentylamine and the mixture was allowed to stand overnight. The precipitated crystals were separated by filtration and washed thoroughly with n-hexane to obtain 5.4 g of the title compound.
