6-Chloro-1-({[(2E)-2-methyl-3-phenylprop-2-en-1-yl]oxy}methyl)-1,2,3, 4-tetrahydroquinazoline-2,4-dione

Abstract

In the title compound, C19H17ClN2O 3, the conformation about the ethylene 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 molecule has an open conformation as these substituents are directed away from each other. In the crystal, centrosymmetrically related molecules 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 interactions [ring centroid(N2C4)⋯centroid(C6) distance = 3.5820 (11) Å].
