Research output: Contribution to journalArticlepeer-review


An efficient synthesis of [fluoroacetyl-18F]fluoromelatonin (NΩ)-[18F]Fluoroacetyl-5-methoxytryptamine) starting from [18F]fluoride and ethyl p-toluensulfonyloxyacetate is described. The total time required for its synthesis is ca. 90 min. The radiochemical yield, purity and specific activity (end of bombardment) of the desired compound are 14.2%, > 98%, and 540 mCi/μmol, respectively.
