Abstract
In the title compound, C19H17ClN2O3, the conformation about the ethylene bond [1.333 (2) A(degrees)] is E. The ten atoms comprising the quinazoline ring are essentially planar (r.m.s. deviation = 0.032 A(degrees)) and their mean plane forms a dihedral angle of 13.89 (7)(degrees)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 threedimensional architecture by C-H...O, C-H...and pi-pi interactions [ring centroid(N2C4)...centroid(C-6) distance = 3.5820 (11) A(degrees)].
