Reaktionsschritte

A solution of 3.9 g of p-chloro-α,α-dimethylbenzyl isocyanate, prepared from the corresponding cyanide in the same way as in Synthesis Example 1, in 20 ml of methyl isobutyl ketone was added to 2.2 g of N-n-butylethylamine. The solvent was then removed by distillation under reduced pressure and the resulting crystals were recrystallized from n-hexane to obtain 5.1 g of the title compound.
