Method for synthesizing labelled compounds
First Claim
1. A process for synthesizing labeled compounds with an isotopic element, comprising the steps of:
- preparing a labelling agent;
labelling a precursor with the labelling agent, wherein the precursor is a protected substrate;
pre-purifying the labelled precursor;
retaining the labelled precursor on a solid support;
deprotecting the labelled precursor, wherein deprotecting the labelled precursor converts the labelled precursor into a labelled compound in a deprotection step, wherein the labelled compound is free of the solid support; and
formulating a final solution, wherein the deprotection step is performed directly on the solid support which is contained in a column or cartridge and wherein the labelled compound is 2-[18F]fluoro-2-deoxy-D-glucose (FGD).

Abstract
A process and a device for synthesizing labeled compounds. The process involves preparing a labeling agent, labeling a precursor with the labeling agent, where the precursor is a protected substrate, and deprotecting the labeled precursor to convert the labeled precursor to a labeled compound by passing the labeled precursor through a solid support in a column or a cartridge. The process may be used to convert labeled tetraacetylfluoroglucose (TAFg) to labeled fluoro-deoxy-glucose (FDG) for use in nuclear medical imaging. The process is more rapid than conventional methods and is performed at room temperature rather than high temperature for conventional technology.
