该中间体在本合成路线中的序号:(X)The synthesis of the 125I-labeled compound is shown in Scheme 2. Carboxylic acid (IV) was coupled with 3-(tri-n-butylstannyl)benzylamine (VIII) via the mixed anhydride (V) to produce amide (IX). Subsequent oxidation with oxone afforded the sulfone (X). Finally, iododestannylation of (X) employing Na125I and chloramine-T furnished the radiolabeled compound.
