This paper describes the radiosynthesis of [C-11]CGP62349, a potential ligand to assess GABA, receptors in vivo. C-11 was introduced by O-methylation of the corresponding des-methyl precursor, namely CGP67780. The final product was obtained with a reliable method in good yield. The radioligand was tested in monkey, revealing negligible blood brain barrier penetration and brain uptake, thus prompting us to search for a new target structure with a better lipophilicity.

C-11 was introduced by O-methylation of the corresponding des-methyl precursor, namely CGP67780. The final product was obtained with a reliable method in good yield. The radioligand was tested in monkey, revealing negligible blood brain barrier penetration and brain uptake, thus prompting us to search for a new target structure with a better lipophilicity.
