| Popis: | 6-(2-Fluorophenyl)-N-(p-tolyl)imidazo[1,2-a]pyridine-2-carboxamide is an organic intermediate having both functions of azabicyclo and amide groups. In this paper, the title compound is obtained by the ring closure reaction, the Suzuki reaction, the hydrolysis and amidation reactions. The structure of the compound is confirmed by FT-IR, 1H NMR, 13C NMR spectroscopy, and MS. At the same time, a single crystal of the title compound is measured by X-ray diffraction and subjected to crystallographic and conformational analyses. The molecular structure is further calculated using density functional theory (DFT) and compared with the X-ray diffraction value. The results of the conformation analysis indicate that the molecular structure optimized by DFT is consistent with the crystal structure determined by single crystal X-ray diffraction. In addition, the molecular electrostatic potential and frontier molecular orbitals of the title compound are further investigated using DFT, revealing some physicochemical properties of the compound. |
