N‐(1‐methyl‐2‐oxo‐5‐phenyl‐2,3‐dihydro‐1H‐benzo[e][1,4]diazepin‐3‐yl)‐benzamide‐[carboxyl‐14C] has been synthesized from benzonitrile‐[cyano‐14C]. Copyright © 2005 John Wiley & Sons, Ltd.

Four bis(heteroaryl)piperazines labeled with carbon-14 in the 2-position of imidazole moiety were prepared as part of a 4-step (or 5-step) sequence from 5-hydroxymethyl-2-mercapto-1-benzylimida-zole-[2-14 C] as a key synthetic intermediate which has been synthesized from potassium [14 C]-thiocyanate.
