**4. Materials and Methods**

#### *4.1. General Information*

All reagents were obtained from commercial sources and used without further purification. Acetonitrile, toluene and N,N-dimethylformamide were distilled from suitable drying agents (CaH2 or P2O5) and stored over MS 4Å. Mass spectra were recorded with

a Bruker Maxis HRMS-ESI-qTOF spectrometer (Moscow, Russia) (electrospray ionization mode). NMR data were recorded with Bruker Avance 400/500 spectrometer (Moscow, Russia) (400.13 MHz for 1H, 100.61 MHz and 125.73 MHz for 13C and 376.50 MHz for 19F) in DMSO-d6 and were referenced to residual solvent proton peaks (δH = 2.51 ppm) and solvent carbon peaks (δC = 39.52 ppm). NMR and HRMS spectra are in the Supplementary Material.
