Abstract

The radiochemical synthesis of 2-[18F]fluoro-3-(2(S)- azetidinylmethoxy)pyridine (2-[18F]A-85380, [18F]1) was accomplished by Kryptofix® 222 assisted nucleophilic no-carrier-added [18F]fluorination of 2-iodo-3-((1-tert-butoxycarbonyl-2(S)-azetidinyl)methoxy)pyridine, 2 followed by acidic deprotection. The average radiochemical yield was 10% and the average specific radioactivity was 1050 mCi/μmol, calculated at end-of- synthesis (EOS).
