The synthesis of methyl 15-(4-trimethylstannylphenyl)pentadecanoate (p-SnPPA), a precursor for the regiospecific production of 15-(4-[123I]-iodophenyl)pentadecanoic acid, is described. The stannylated precursor is synthesized in six steps from 4-bromophenylacetylene in an overall yield of 16%. p-SnPPA reacts with N.C.A. [123I]NaI in the presence of peracetic acid to yield IPPA in 62% radiochemical yield following hydrolysis.
