## Abstract A series of ^11^C‐labeled ureas was prepared using a rapid and efficient one‐pot procedure. First, the intermediate [^11^C]phenylisocyanate was formed with phenyltriphenylphosphinimine and [^11^C]CO~2~. A range of amines was then reacted with the [^11^C]phenylisocyanate yielding the [^1
