Abstract

Tritiated (S)‐10‐bromoacetamidomethylcamptothecin was prepared starting from (S)‐10‐hydroxycamptothecin. The key step consisted of palladium catalyzed direct tritium exchange on the intermediate (S)‐10‐aminomethylcamptothecin. ^3^H NMR spectroscopy indicated the tritium label was located exclusively at the C‐5 position.
