Abstract: In the title compound, C18H15N3O5S, the approximately planar quinazoline ring system [maximum deviation = 0.097 (3) Å] forms a dihedral angle of 76.53 (19)° with the phenyl ring. The terminal -C(=O)-O-C group is disordered over two sets of sites with a site-occupancy ratio of 0.811 (17):0.189 (17). In the crystal, molecules are linked via weak C-H...O hydrogen bonds into sheets parallel to the ac plane.
