dissymmetrical biselectrophilic reagent, p-(chloromethyl)benzyl-p-toluenesulfonate, with phosphorylcyclam to give rise to an original intermediate possessing a p-chloroxylenyl pendant arm. The subsequent reaction of this compound with glyoxal-protected lineartetraamine, followed by deprotection steps, leads to the desired ditopic ligand with a good overall yield.
