## Abstract A simple and convenient method for the synthesis of carbonโ€^14^ labeled diphenylhydantoin (DPH) (I) and its major metabolite 5โ€(pโ€hydroxyphenyl)โ€5โ€phenylhydantoin (HPPH) (II) in 70 minutes is described. This synthesis allows incorporation of carbonโ€11โ€^11^ (physical halfโ€life 20 minutes
