✦ Synopsis

Flunarizine, a calcium channel antagonist of the piperazine class, has been labeled with the positron-emitter 18F.4-[18F]Fluoro-4-fluorobenzhydryl chloride was prepared in three steps from no-carrier-added [18F]fluoride ion, and used in the alkylation of N-cinnamylpiperazine to give [18F]flunarizine in 13% radiochemical yield (from [18F]fluoride).

Fluorination with 18F-F2 and 18F-AcOF were compared for the synthesis of 18F-fluorophenylalanines. L-phenylalanine in CF,COOH trapped 18F-AcOF more effectively than 18F-F2. The main product was ortho-18F-fluorophenylalanine when 18F-AcOF was used as a reagent. Lower radiochemical yield of 18F-fluoro

The radiochemical synthesis of [18F]Fluororaclopride (S-3,5-dichloro-6-methoxy-N-(1-(2-[18F]fluoroethyl)-2-pyrrolidinylmet hyl) salicylamide) is accomplished via a two step synthesis. [18F]Fluoroethyltriflate is prepared by [18F]fluoride displacement on the bis triflate of ethylene glycol. [18F]Fluo
