PRÉCURSEUR MARQUÉ AU18-F POUR SUBSTANCES RADIOACTIVES À USAGE MÉDICAL UTILISÉES EN TOMOGRAPHIE PAR ÉMISSION DE POSITONS ET SON PROCÉDÉ DE PRÉPARATION

The present invention relates to a precursor of positron emission tomography (PET) radioactive medical supplies, a preparation method thereof, and an application thereof, and more specifically, to a precursor having a tetravalent organic salt leaving group, a preparation method, and a method for preparing desired PET radioactive medical supplies in a high radiochemical yield within a short preparation time by introducing¹⁸F using the same through a single step. The precursor having a tetravalent organic salt leaving group of the present invention can simplify the known complex multistep preparation of radioactive medical supplies into a single step, can save production costs because an excessive amount of a phase transfer catalyst is not required, facilitates separation of compounds after reaction, and enables rapid reaction velocity. The features are appropriate for the mass production of PET radioactive medical supplies by an automated synthesis system.
