A convenient synthesis of a bifunctional derivative of the ligand NOTA is described. The synthesis offers advantages over current literature methods for making similar molecules by starting with the easily prepared ortho-amide of 1,4,7-triazacyclanonane which can be sequentially alkylated to provide a bifunctional NOTA derivative in 9% yield overall. The replacement of preparative HPLC with simple ion-exchange chromatography provides analytically pure ligand suitable for clinical applications.
