| Reactant | N-Methylisobutylamine | HCID 12249 | — |
| Reactant | 1-Chloro-4-(2-isocyanatopropan-2-yl)benzene | HCID 13118323 | — |
| Product | 1-i-Butyl-3-(p-chloro-alpha,alpha-dimethylbenzyl)-1-methylurea | HCID 54536681 | 92.2% |
Reaction Steps
3.9 g of p-chloro-α,α-dimethylbenzyl isocyanate, prepared from the corresponding cyanide in the same way as in Synthesis Example 1, was added to 1.9 g of N-i-butyl-N-methylamine. The precipitated crystals were separated by filtration and recrystallized from n-hexane to obtain 5.2 g of the title compound.
