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