This report describes the synthesis of radioiodinated 1-carboxamidino-4-phenylpipera-zine——a new adrenomedullary imaging radiopharmaceutical.
To 4-phenylpiperazine in water a slight excess of s-methyl-thiouronium sulfide
was
added. The solution was heated at reflux for 6h and then cooled to room temperature
The precipitate formed was collected and recrystallized from hot water. This compound was radioiodinated by the chloramine-T method. The iodinated tracer was purified by paper chromatography. The yield was about 86% (from 83% to 89%). The radiochemical purity was over 98%.
