Source of material
All reagents were of analytical grade and used as purchased without further purification. A mixture of amino-6-nitrobenzoic acid (0.010 mol, 1.8210 g) and formamide (0.100 mol, 4.5020 g) in a microwave reaction vessel was heated in a microwave reactor at 140 °C for 1 h. The resulting mixture was cooled to room temperature, filtered, washed with water and dried at 50 °C for 10 h in vacuum oven to obtain the title compound of formula. Yield: 86.3%. M. pt: 523–527 K. 1H NMR (DMSO-d6, 400 MHz): δ12.72 (br.s, 1H), 8.28 (s, 1H, H-2), 7.76 (t, J = 8.4 Hz, 1H), 7.41 (d, J = 7.8 Hz, 1H), 7.32 (d, J = 8.4 Hz, 1H). The solid was recrystallized in EtOH and yellow block crystals of the title compound were obtained by slow evaporation over a period of 1 week. Elemental analysis Anal. Calcd. for C8H5N3O3: C, 50.27; H, 2.64; N, 21.98%. Found: C, 50.30; H, 2.63; N, 21.90%.
Experimental details
The structure was solved by Shelxt. Absorption corrections were applied by using multi-scan program [1]. All the hydrogen atoms were fixed geometrically and allowed to ride on their attached atoms with Uiso = 1.2Ueq of the attached atoms.
Comment
Quinazoline is an important intermediate for drugs synthesis and its derivatives exhibit many pharmaceutical performances including antifungal [5, 6], antibacterial [7], anti-virus [8], and antimicrobial [9], antiprotozoal activities [10]. Furthermore, the compounds may possess antitumor properties that they showed potent anticancer activity at low concentrations [11], [12], [13].
The asymmetric unit of the title compound C8H5N3O3 is a fused aromatic molecule (see the figure). The nitro group is not co-planar with the core to which it is connected as seen in the value of the O2–N3–C7–C6 torsion angle of 62.8(3)°. The benzo moiety is not completely coplanar with the pyrimidine moiety due to the steric hindrance effect of the nitro group, showing a slight puckering conformation. The plane comprising C6, C7 and C8 makes a dihedral angle of 8.5(4)° with the plane formed by N1, C1 and C8. The C–N bond lengths fall in the range of 1.286(3) to 1.477(3) Å that are in agreement with that found in [C16H13N3O3] [14]. The O2–N3–O3 bond angle is 124.3(2)°, and the C–N–C bond angles range from 116.1(2)° to 123.6(2)°, which are comparable with the values for similar compounds [15–17]. In the crystal structure, intermolecular hydrogen bonds (N1–H1⋯O11: 2.831(2) Å and 167.2°: 1 − x, 2 − y, 1 − z) link the adjacent molecules into centrosymmetric dimers.
