6-Chloro-1-({[(2E)-2-methyl-3-phenyl-prop-2-en-1-yl]-oxy}meth-yl)-1,2,3,4-tetra-hydro-quinazoline-2,4-dione.
In the title compound, C(19)H(17)ClN(2)O(3), the conformation about the ethyl-ene bond [1.333 (2) Å] is E. The ten atoms comprising the quinazoline ring are essentially planar (r.m.s. deviation = 0.032 Å) and their mean plane forms a dihedral angle of 13.89 (7)° with the terminal phenyl ring; the mol-ecule has an open conformation as these substituents are directed away from each other. In the crystal, centrosymmetrically related mol-ecules are connected via N-H⋯O hydrogen bonds between the amide groups, leading to eight-membered {⋯HNCO}(2) synthons. These are consolidated into a three-dimensional architecture by C-H⋯O, C-H⋯π and π-π inter-actions [ring centroid(N(2)C(4))⋯centroid(C(6)) distance = 3.5820 (11) Å].
