Abstract:
An improved, automated synthesis of [(18)F]FDOPA including four synthetic steps (fluorination, reductive iodination, alkylation and hydrolysis) is reported with each step optimized individually. In a home-made automatic synthesizer, 9064+/-3076 MBq of [(18)F]FDOPA were produced within 120 min from EOB (n=5). Radiochemical purity and enantiomeric excess were both >or= 95%. Specific activity was ca. 50 GBq/micromol at EOS. This automatically operable synthesis is well suited for the multi-patient-dose routine production of n.c.a. [(18)F]FDOPA.
