How is 3-[(Ethoxycarbonyl)amino]phenyl phenylcarbamate (CAS: 13684-56-5) typically synthesized?

3-[(Ethoxycarbonyl)amino]phenyl phenylcarbamate is typically synthesized through a multistep process involving the coupling of a phenylcarbamate derivative with a 3-(ethoxycarbonylamino) phenylamine. Common solvents include dichloromethane, and the reaction is catalyzed by a suitable base such as triethylamine. The yield is generally high, around 85-90%, and the method involves protecting groups and careful temperature control.
