4, the two quinazoline heterocyclic systems and the adjacent chlorobenzene rings are not coplanar, but oriented at dihedral angles of 66.66 (13) and 52.48 (12)°, respectively. The quinazoline ring systems are nearly planar, with dihedral angles between the planes of the two rings of 5.43 (16) and 3.40 (14)°, and are oriented at dihedral angles of 79.73 (13) and 83.52 (13)° with respect to the adjacent benzene ring between them. Intermolecular C—H

O hydrogen bonds contribute to the stability of the structure. In addition, weak π–π stacking interactions [centroid-to-centroid distances = 3.872 (1) and 3.876 (1) Å] are observed in the crystal structure.

To a solution of iminophosphorane (1.40 g, 3.0 mmol) in anhydrous THF (10 ml)
was added 4-chlorophenyl isocyanate (3 mmol) under nitrogen at room
temperature. After reaction, the mixture was allowed to stand for 10 h at
273–278 K, the solvent was removed under reduced pressure and diethyl
ether/petroleum ether (1:2 v/v, 20 ml) was added to precipitate
triphenylphosphine oxide. After filtration, the solvent was removed to give
1-(4-chlorophenyl)-3-(2-ethoxycarbonylphenyl) carbodiimide, which was used
directly without further purification. To a solution of
1-(4-chlorophenyl)-3-(2-ethoxycarbonylphenyl) carbodiimide in THF (15 ml) was
added m-dihydroxybenzene (0.18 g, 3 mmol). After the reaction mixture
was allowed to stand for 0.5 h, the solvent was removed and anhydrous ethanol
(10 ml) with several drops of EtONa in EtOH was added. The mixture was stirred
for 2 h at room temperature. The solution was concentrated under reduced
pressure and the residue was recrystallized from ethanol to give the title
compound, (I). The product was recrystallized from methanol–dichloromethane
(1:1 v/v, 20 ml) at room temperature to give crystals suitable
for X-ray diffraction [m.p. 444 K, yield 45%].
All H atoms were located in difference maps and treated as riding atoms with
C—H = 0.93 Å, Uiso = 1.2Ueq(C) for Csp2.

Special details top
Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes)
are estimated using the full covariance matrix. The cell e.s.d.'s are taken
into account individually in the estimation of e.s.d.'s in distances, angles
and torsion angles; correlations between e.s.d.'s in cell parameters are only
used when they are defined by crystal symmetry. An approximate (isotropic)
treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s.
planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor
wR and goodness of fit S are based on F2, conventional
R-factors R are based on F, with F set to zero for
negative F2. The threshold expression of F2 >
σ(F2) is used only for calculating R-factors(gt) etc.
and is not relevant to the choice of reflections for refinement.
R-factors based on F2 are statistically about twice as large
as those based on F, and R- factors based on ALL data will be
even larger. |

Quinazoline derivatives have broad biological properties. Some of these activities include antimicrobial (Pandeya et al., 1999; Shiba et al., 1997), antidiabetic (Malamas & Millen, 1991), anticonvulsant (Mannschreck et al., 1984), antibacterial (Kung et al., 1999), antifungal (Bartroli et al., 1998), protein tyrosine kinase inhibitors (Palmer et al., 1997), EGFR inhibitors (Tsou et al., 2001) and PDGFR phosphorylation inhibitors (Matsuno et al., 2002). We have recently focused on the synthesis of heterocyclic compounds using an aza-Wittig reaction. We present here the synthesis and the crystal structure of the title compound, (I) (Fig. 1), which can be used as a precursor for obtaining bioactive molecules.
In the crystal structure of (I), the quinazoline heterocycle N1—C7/C8–C13/N2—C14 and N3—C22/C23–C28/N4—C21 and the adjacent chlorobenzene ring C1–C6 and C29–C34 are not co-planar, but oriented at the dihedral angles of 66.66 (13) and 52.48 (12)°, respectively. The nearly planar quinazoline ring system N1—C7/C8–C13/N2—C14 and N3—C22/C23–C28/N4—C21 are oriented with respect to the adjacent ring C15–C20 at the dihedral angles of 79.73 (13) and 83.52 (13)°, respectively.
Significant intramolecular C—H···O hydrogen bonds contribute to the stability of the molecular configuration (Fig. 2 and Table 1). The crystal structure (Fig. 2) is also stabilized by weak π–π (Table 1) stacking interactions with centroid–centroid separations of 3.872 (1) and 3.876 (1) Å for Cg2···Cg2i and Cg2···Cg6i, respectively, where Cg2 and Cg6 are the centroids of rings N3/C21—N4/C28—C27/C22 and C22–C27, respectively [symmetry code: (i) 1 - x, -y, 1 - z].
