초록

We developed simple and highly efficient synthesis method for [$^{11}C$]methionine using solid-phase extraction method. For synthesis, we used C18 cartridge. [$^{11}C$]methionine was synthesized on C18 cartridge according to the solid-phase [$^{11}C$]methylation of precursor L-homocysteine thiolactone hydrochloride. The radiochemical yields of [$^{11}C$]methionine was $48.9{\pm}7.93%$ decay corrected (results of 30 syntheses, mean$\pm$SD), with average production higher than 180 mCi. This procedure showed high yield and simple synthesis of [$^{11}C$]methionine.
