The solvents were purified according to the standard procedures. All starting materials were obtained from Enamine Ltd. Melting points were measured on MPA100 OptiMelt automated melting point system. Analytical TLC was performed using Polychrom SI F254 plates. Column chromatography was performed using Kieselgel Merck 60 (230-400 mesh) as the stationary phase 1 H, C{ 1 H}, F{ 1 H} NMR, and 2D NMR spectra were recorded on an Agilent ProPulse 600 spectrometer (at 600 MHz for 1 H NMR and 151 MHz for 13 C{ 1 H} NMR), a Bruker 170 Avance 500 spectrometer (at 500 MHz for 1 H, 126 MHz for C, and 470 MHz for 19 F), or a Varian Unity Plus 400 spectrometer (at 400 MHz for 1 H, 101 MHz for C, and 376 MHz for 19 F). NMR chemical shifts are reported in ppm (δ scale) downfield from TMS as an internal standard and are referenced using residual NMR solvent peaks at 7.26 and 77.16 ppm for 1 H and C in CDCl3, 2.50 and 39.52 ppm for 1 H and C in DMSO-d6. Coupling constants (J) are given in Hz. Spectra are reported as follows: chemical shift (δ, ppm), multiplicity, integration, coupling constants (Hz). Elemental analyses were performed at the Laboratory of Organic Analysis, Department of Chemistry, Taras Shevchenko National University of Kyiv. Mass spectra were recorded on an Agilent 1100 LCMSD SL instrument (chemical ionization (CI)) and Agilent 5890 Series II 5972 MS instrument (electron impact ionization (EI)). High-resolution mass spectra (HRMS) were obtained on an Agilent 1260 Infinity UHPLC instrument coupled with an Agilent 6224 Accurate Mass TOF mass spectrometer.
