3.2.4. Synthesis of Dimeric FSC-based Tz Hybrid Imaging Agents

Conjugation of the fluorescent dye to the dimeric FSC-based Tz-ligand was performed as described above using 1.0 mg of [Fe]FSC-(PEG5-Tz)<sup>2</sup> (0.57 µmol) as starting material. After successful conjugation, demetallation was performed as described above followed by purification via preparative RP-HPLC. Analytical data:
