Nucleophilic radiosynthesis of boron neutron capture therapy-oriented PET probe [18F]FBPA using aryldiboron precursors.

A reliable copper-mediated nucleophilic radiosynthesis of the PET imaging probe [18F]FBPA was developed using novel aryldiboron precursors. The carrier-free [18F]FBPA with radiochemical purity >99% was prepared routinely via the two-step synthesis with an automatic module and can be used for clinical PET imaging of tumours.
