2-Chloro-N-(2-chloro­benzo­yl)-N-(2-ethyl-4-oxo-3,4-di­hydro­quinazolin-3-yl)benzamide

In the title compound, C(24)H(17)Cl(2)N(3)O(3), the quinazolinone ring system is close to planar (r.m.s. deviation = 0.0132 Å), with the imide unit almost perpendicular to it, subtending a dihedral angle of 89.1 (1)°. However, the imide unit itself is not planar, the dihedral angle between the two O=C—N components being 34.6 (1)°. The dihedral angle between the two chlorobenzene rings is 40.50 (7)°, while the angles between these rings and the imide moiety are 54.6 (1) and 58.2 (1)°, respectively. The dihedral angles between the 2-chloro­phenyl rings and the quinazolinone ring system are 48.77 (5) and 32.92 (7)° for rings A and B, respectively. In the crystal, weak C—H⋯O inter­actions link the mol­ecules into a three-dimensional array.
