Aromatic nucleophilic substitution of various trimethylammonium trifluoromethanesulfonates with [18F]fluoride has been evaluated. Fluorinations were studied over a temperature range of 45-165.degree. C, with decay corrected yields ranging from 20-80%. [18F]GBR 13119, 1-[2-{(4-[18F]fluorophenyl)(phenyl)methoxy}ethyl]-4-(3-phenylpropyl)piperazine, a potential radiotracer for the dopamine uptake system, has been prepared in no-carrier-added form from 4-N,N,N-trimethylaniliniumphenylmethanone trifluoromethanesulfonate. Purification by solid-phase techniques yielded the product in 20% decay corrected radiochemical yield and > 98% radiochemical and chemical purity without HPLC.
