    • Alternatively, CuAAC can be performed with the fully protected intermediate obtained from the coupling reaction of DOTA(tBu)3-NHS ester with precursor 13; however, this requires application of a carefully optimized synthetic procedure, which we recently reported (Ref. [29]). Subsequent removal of the protecting groups (N(a)-Boc of Lys and tertbutyl ester of DOTA) by treatment with TFA followed by complexation with GdCl3 gave L22 in similar yields (see Supporting Information for details)
