Simple automated system for simultaneous production of 11C-labeled tracers by solid supported methylation

We herein describe a simple setup for the automated simultaneous synthesis of l-[methyl-11C]methionine and N-[methyl-11C]choline by solid-supported methylation . The setup is extremely simple and easy to adapt to other automated systems and due to its versatility, the method can be utilized for the production of other radiopharmaceuticals requiring a simple [11C]methylation step. Furthermore, it can be used for multiple simultaneous synthesis.
