FIELD: chemistry.
SUBSTANCE: invention relates to methods and reagents of labelling a vector such as a peptide, involving reaction of a compound of formula
with a compound of formula R*-L2-N3 (II) in the presence of a Cu (I) catalyst.
EFFECT: obtained labelled conjugates are useful as diagnostic agents, for example, as radiopharmaceutical preparations, more specifically for use in positron emission tomography (PET) or single-photon emission computed tomography (SPECT) or for radiotherapy.
