合成路线1
该中间体在本合成路线中的序号:(II)The title ternary ligand technetium-99m complex was formed as a mixture of two isomeric forms by reaction of the hydrazinonicotinamide-derivatized cyclic peptide (I) with trisodium triphenylphosphine-3,3',3''-trisulfonate (II) and tricine (III) in the presence of 99mTc pertechnetate and SnCl2. The 99Tc analogue was similarly prepared for spectroscopic characterization by using (n-Bu4N)(99TcOCl4) or (NH4)(99TcO4).

合成路线2
该中间体在本合成路线中的序号:(II)The title compound was then obtained by complexation of hydrazone (IX) with phosphine (II) and tricine (III) in the presence of Na99mTcO4 and SnCl2. Under these conditions, the hydrazone protecting group hydrolyzed to the required hydrazine. Some shortcomings caused by SnCl2 could be omitted using a non-SnCl2-containing formulation in the presence of mannitol and pluronic acid as surfactant agents.

合成路线3
该中间体在本合成路线中的序号:(III)The title compound was synthesized from the known formyl tetrapeptide conjugated to 6-hydrazinonicotinic acid (I) by complexation with tricine (II), trisodium triphenylphosphine-3,3',3''-trisulfonate (III) and sodium 99mTc-pertechnetate, either in two steps by first complexation of the stannous chloride-reduced technetium with (I) and (II), and then reaction with (III), or in one step by direct reduction of Na99mTcO4 with SnCl2 in the presence of (I), (II) and (III). The compound was also formed in the absence of SnCl2.
