How is S-Ethyl cyclohexyl(ethyl)carbamothioate (CAS: 1134-23-2) typically synthesized?

S-Ethyl cyclohexyl(ethyl)carbamothioate can be synthesized via an amide carbamation process, where cyclohexylamine reacts with ethyl isothiocyanate in the presence of a base such as pyridine. The reaction is typically carried out at room temperature, and the yield can be up to 80%. The process requires mild conditions and can be optimized for better selectivity and higher yields.
