[en] We modified a commercially available synthesis module for nucleophilic ["1"8F]fluorinations (TRACERlab"T"M FX_F_D_G, GE Healthcare) to enable the reliable synthesis of 2-["1"8F]fluoro-4-borono-L-phenylalanine (["1"8F]FBPA) via direct electrophilic substitution of 4-borono-L-phenylalanine with ["1"8F]F_2 gas. ["1"8F]FBPA was obtained with a RCY of 8.5±2.0% and a radiochemical purity of 98±1% in a total synthesis time of 72±7 min (n=22). The modified synthesis module might also be useful for the synthesis of other ["1"8F]radiopharmaceuticals via electrophilic substitution reactions while still being suitable for nucleophilic substitution reactions. - Highlights: • Automated synthesis of ["1"8F]FBPA was developed via reaction of BPA with ["1"8F]F_2. • ["1"8F]FBPA was obtained with a RCY of 8.5±2.0%. • Nucleophilic synthesis module was adapted for electrophilic ["1"8F]fluorinations. • Modified synthesis module may also enable other electrophilic ["1"8F]fluorinations
