Abstract

6-Chloro-3-((2-(S)-azetidinyl)methoxy)-5-((E)-2-(2- [18F] fluoropyridin-4-yl)vinyl)pyridine ([18F]NIDA 52289), a very high affinity radioligand for studying nicotinic acetylcholine receptors (nAChRs) by positron-emission tomography, was synthesized through Kryptofix 222 assisted no-carrier-added nucleophilic [18F]fluorination of 6-choro-3-((l-(tert-butoxycarbonyl)-2-(S)-azetidinyl)methoxy)-5-((E) -2-(2-bromopyri-din-4-yl)vinyl)pyridine, followed by acidic deprotection. The overall radiochemical yield of the radiosynthesis was 10% (non-decay-corrected), the specific radioactivity was in the range of 93-326 GBq/μmol (2.5-8.8mCi/μmol) and the radiochemical purity was greater than 99%.
