Participants

Reaction Steps

A mixture of 5 parts of cyclohexyl 4,4-dimethylthioallophanimidate and 4 parts t-butylisocyanate in 70 parts of methylene chloride is refluxed for 2 hours. After evaporation of the solvent, the oily residue is triturated with petroleum-ether to give solids, which are recrystallized from cyclohexane to give pure cyclohexyl N-dimethylcarbamoyl-4-t-butylthioallophanimidate (a compound of formula I).
