[en] The syntheses of o- and p- [18F]fluorobenzyl bromides as labelled synthons were described. They were obtained from nitrobenzaldehyde via a three step synthesis that exhibited good yield. The preparation of [18F]fluororinated analog of a benzamide neuroleptic, cis-N-[(2RS, 3RS)-1-[18F]fluorobenzyl-2-methyl-pyrrolidin-3-yl]-5-chloro-2-methoxy-4-methylaminobenzamide, via N-benzylation with the synthons was also mentioned.
