PEREZ-FEHRMANN, MARCIA et al. ¹H AND ¹³C NMR SPECTRAL ASSIGNMENTS AND X-RAY CRYSTALLOGRAPHY OF N-(3-(1H-IMIDAZOL-1-YL)PROPYL)-2-PHENYLQUINAZOLIN-4-AMINE. J. Chil. Chem. Soc. [online]. 2013, vol.58, n.2, pp.1771-1774. ISSN 0717-9707.  http://dx.doi.org/10.4067/S0717-97072013000200029.

N-(3-(1H-Imidazol-1-yl)propyl)-2-phenylquinazolin-4-amine (2) was obtained by nucleophilic substitution of 1-(3-aminopropyl)-imidazole over 4-chloro-2-phenylquinazoline (1) with DMF/TEA at room temperature. The precursor and product were characterized by NMR spectroscopy. The structure of the title compound was confirmed by X-ray diffraction methods. The quinazoline fragment (2) is essentially planar and makes a dihedral angle of 66.35 ° with the imidazole plane. In the crystal packing the molecules are associated by two strong intermolecular NH----N hydrogen bonds with graph-set motif R²₂(16). These pairs are linked by two π-π interactions.
