Procedure

For protecting thiol groups, take 2-thioethylamine hydrochloride and triphenylmethanol as reactants and boron trifluoride-diethyl ether complex is used as a catalyst to get 2-[(triphenylmethyl)thio]ethylamine. The reaction temperature is 72 degrees Celsius and the reaction time is 4 hours. Step (2): Use 2-[(Triphenylmethyl)thio]ethylamine and chloroacetyl chloride to carry out the amidation reaction in trichloromethane solution so as to produce N-[2-((Triphenylmethyl)thio)ethyl]-chloroacetamide. Step (3): Take 2-[(Triphenylmethyl)thio]ethylamine, N-[2-((Triphenylmethyl)thio)ethyl]-chloroacetamide and use triethylamine used as a reagent to carry out the substitution reaction in dichloromethane solution. Thus an amine-amide-thiol ligand is produced. The reaction temperature of the substitution reaction is 55° C. and the reaction time is 48 hours. Step (4): Dissolve 6-bromohexanoic acid and thionyl chloride in absolute methanol solution to carry out the esterification reaction and get methyl 6-bromohexanoate. The reaction temperature of the esterification reaction is 25° C. and the reaction time is 24 hours. Step (5): Take the amine-amide-thiol ligand and methyl 6-bromohexanoate and use sodium hydroxide (NaOH) as a reagent to carry out the substitution reaction in acetonitrile solution and get methyl 7,10-diaza-9-oxo-7-[2-((triphenylmethyl)thio)-ethyl]-12-[(triphenylmethyl)thio]dodecanoate. The reaction temperature of the substitution reaction is 85° C. and the reaction time is 24 hours. Step (6): Hydrolyze methyl 7,10-diaza-9-oxo-7-[2-((triphenylmethyl)thio)-ethyl]-12-[(triphenylmethyl)thio]dodecanoate in alkaline methanol solution to get 7,10-diaza-9-oxo-7-[2-((triphenylmethyl)thio)-ethyl]-12-[(triphenyl-methyl)thio]dodecanoic acid.
