Abstract

No‐carrier‐added 2‐(4‐[^131^I]iodophenyl)‐ and 8‐[^131^I]iodo‐2‐phenylpyrazolo[4,3‐c]quinolin‐3(5H)‐one were prepared in isolated radiochemical yields of 11.6 and 5.4%, respectively, by acid decomposition of aryl triazenes in acetonitrile. A modified triazene method involving solid‐phase decomposition reactions increased the isolated radiochemical yields to 15–35%.
