1 Source of material

2-Amino-N-(pyridin-2-yl)benzamide (213.24 mg, 1 mmol) and pyridine-2-carboxaldehyde (107.11 mg, 1 mmol) were dissolved in ethanol (10 mL) and the mixture was refluxed for 4 h. The reaction mixture was concentrated in vacuum, and the title compound was isolated through a silica gel column chromatography (PE: EtOAc = 3:1) as a white solid (120.64 mg, 40 % yield). Single crystals of the product can be obtained by recrystallization in ethanol through slow evaporation within 3 days.

2 Experimental details

All hydrogen atoms were identified in difference Fourier syntheses. The U iso values of all hydrogen atoms were set to 1.2U eq (C).

3 Comment

2,3-Dihydroquinazolin-4(1H)-ones are components of many bioactive molecules with broad-spectrum pharmacological properties, such as anti-malaria, anti-cancer, anti-microbial, anti-hypertension, anti-oxidation, anti-inflammatory and so on. 4 , 5 , 6 , 7 , 8

The crystal structure reveals that the title molecule is non-planar. Plane I (C1–C6) forms a dihedral angle of 35.443(8)° with plane II (C8–N3), and 86.885(7)° with plane III (C14–N4). The dihedral angle between plane II and plane III is 89.799(9). The C(13) atom is sp3 hybridized and R-type chiral carbon. The bond lengths of O(1)–C(7) and C(1)–C(7) are 1.226(2) Å and 1.484(3) Å. The sp3 C(13)–N(1), C(13)–N(2) bond lengths are 1.430(2) Å, 1.471(2) Å, which are longer than the sp2 C(7)–N(2), C(8)–N(2), C(6)–N(1), C(14)–N(4), C(18)–N(4), C(8)–N(3), C(12)–N(3) bond lengths of 1.369(2) Å, 1.421(2) Å, 1.373(3) Å, 1.337(2) Å, 1.354(3) Å, 1.323(3) Å, 1.341(3) Å, respectively. The bond angles of O(1)–C(7)–C(1), O(1)–C(7)–N(2), C(1)–C(7)–N(2), C(6)–N(1)–C(13), C(8)–N(3)–C(12), C(14)–N(4)–C(18), N(2)–C(13)–N(1), N(1)–C(13)–C(14) and N(2)–C(13)–C(14) are 121.13(17)°, 122.92(18)°, 115.82(16)°, 116.92(16)°, 117.6(2)°, 116.91(19)°, 109.16(14)°, 112.91(15)° and 111.59(14)°, respectively. Geometric parameters are all in the expected ranges. 6 , 9
