The benzoyl-protected ligand (IV) was prepared as follows. Acylation of triglycine (I) with chloroacetyl chloride (II) produced the chloroacetamide (III). Subsequent treatment of chloride (III) with sodium thiobenzoate yielded thioester (IV). The title 99technetium complex was prepared by in situ hydrolysis of the thiobenzoate ester (IV) to mercaptoacetyl triglycine (V) in the presence of a solution of [99mTc]pertechnetate, SnCl2 as the technetium reducing species, and gluconate or tartrate as intermediate Tc complexing agents.
