  • Patent number: 8067648
    Abstract: A phenyl tin compound is synthesized by using a derivative having various functional groups and a bromo- or iodo-benzene ring as a labeling material of a radioactive ligand. On the other hand, a novel hydroxytosyl iodobenzene compound having an electron-donating group is obtained by oxidizing iodobenzene having one or more electron-donating groups and reacting it with tosylic acid. Then, a diphenyliodonium salt which is a labeling precursor is synthesized by reacting the resulting compound with various phenyl tin compounds. Finally, a 18F-labeled ligand having various functional groups and a [18F] fluorobenzene ring is synthesized by reacting the resulting diphenyliodonium salt with [18F]F?.
