A solution of 1.2 g of N-methyl-N-cyclohexylamine in 5 ml of n-hexane was added to a solution of 0.01 mole of m-chloro-α,α-dimethylbenzyl isocyanate (prepared from the corresponding cyanide in the same way as shown in Synthesis Example 1) in 10 ml of benzene. The mixture was kept at room temperature for 6 hours and concentrated under reduced pressure to obtain crystals, which were recrystallized from n-hexane to give 2.8 g of the title compound as white crystals.
