ABSTRACT
The title molecule, C22H17BrN2O4S, has a twisted U shape, the dihedral angle between the quinazolin-4-one and bromobenzene ring systems being 46.25 (8)°. In order to avoid steric clashes with adjacent substituents on the quinazolin-4-one ring, the N-bound tolyl group occupies an orthogonal position [dihedral angle = 89.59 (8)°]. In the crystal, molecules are connected into a three-dimensional architecture by C—H...O interactions, with the ketone O atom accepting two such bonds and a sulfonate O atom one.
