合成路线1
该中间体在本合成路线中的序号:(II)This compound has been obtained by two related ways: 1) The hydrolysis of 4'-(bromomethyl)biphenyl-2-carbonitrile (I) with NaOAc in refluxing acetic acid gives the corresponding carbinol (II), which is oxidized with oxalyl chloride in DMSO/dichloromethane yielding the aldehyde (III). The reductocondensation of (III) with L-valine methyl ester (IV) by means of NaBH4CN in THF affords the N-alkylated valine (V), which is acylated with pentanoyl chloride (VI) and TEA in dichloromethane providing the pentanamide (VII). The reaction of the CN group of (VII) with tributyltin azide in refluxing xylene gives the tetrazol derivative (VIII). Finally, the ester group of (VIII) is hydrolyzed with NaOH to furnish the target compound. 2) L-valine methyl ester (IV) can be condensed directly with the bromo-methyl derivative (I) by means of DIEA in dichloromethane giving the N-alkylated valine (V) already reported.

合成路线2
该中间体在本合成路线中的序号:(III)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3
该中间体在本合成路线中的序号:(III)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.
