(Received 1 October 2013; accepted 10 October 2013; online 19 October 2013)

In the title compound, C20H15ClN2, the pyrimidine ring is in a flattened half-chair conformation. The phenyl and chloro-substituted benzene rings form dihedral angles of 84.97 (5) and 80.23 (4)°, respectively, with the benzene ring of the di­hydro­quinazoline group. The dihedral angle between the phenyl and chloro-substituted benzene rings is 61.71 (5)°. In the crystal, mol­ecules are arranged in inter­secting layers parallel to (101) and (-102), with N—H⋯N hydrogen bonds linking mol­ecules along [010]. In addition, a weak C—H⋯π inter­action is observed.

Comment top

Heterocyclic chemistry is a potential part of the synthetic organic chemistry, covering a wide variety of bioactive molecules. Among six-membered heterocycles, quinazoline occupies significant position and is commonly found in a wide variety of natural products, synthetic pharmaceutical molecules, and other functional materials (Gundla et al., 2008; Luth & Lowe, 2008). Quinazoline derivatives are among the most potent tyrosine kinase and cellular phosphorylation inhibitors (Fry et al., 1994), and they also show remarkable activity as antitubercular, antiviral, and anticancer agents (Kunes et al., 2000). The growing medicinal importance of these heterocycles perpetuates to provide strong rationale for the development of synthetic methods for their preparation. These efforts have led to several reviews emphasizing the synthesis (Michael, 2002; Frère et al., 2003; Langer & Bodtke, 2003), and biological evaluation of quinazolines.

In the course of a program directed toward the synthesis of new heterocyclic systems for pharmacological evaluation, we report herein the crystallographic study and the synthesis of the title compound. The molecular structure is shown in Fig. 1. The phenyl ring and chloro-substituted benzene rings form a dihedral angles of 84.97 (5) and 80.23 (4)° respectively with the benzene ring of dihydroquinazoline group. The dihedral angle between the phenyl ring and chloro-substituted benzene ring is 61.71 (5) °. In the crystal, molecules are arranged in intersecting layers parallel to (101) and (-102) (see, Fig. 2) with N—H···N hydrogen bonds linking molecules along [010] (Fig. 3). In addition, a weak C—H···π interaction is observed (Table 1).

Experimental top

The title compound was prepared by condensation of 4-chlorobenzaldehyde (1.0 equiv), 2-aminobenzophenone (1.0 equiv), ammonium acetate (2.0 equiv), and dimethylaminopyridine (0.2 equiv.) in 5 ml of absolute ethanol at 313 K. After completion of the reaction as monitored by TLC, the reaction was poured into ice cold water; solid product was filtered, washed with water and dried. The crude product was recrystallized from ethyl acetate to give the tite compound as a yellow solid (m.p. 415–417 K). X-ray quality crystals were grown from a solution of the title compound in ethyl acetate.

Refinement top

H atoms bonded to C atoms were initially located in a difference Fourier map. However, they were subsequently placed in idealized positions and refined in a riding-model approximation. The applied constraints were as follows: Caryl—Haryl = 0.93 Å; Cmethine—Hmethine = 0.98 Å; Uiso(HarylHmethine) = 1.2Ueq(Caryl/Cmethine). Atom H1N was located in a difference Fourier map and refined isotropically.

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.
