title: 2-Methyl-3-(2-methyl-phen-yl)-4-oxo-3,4-dihydro-quinazolin-8-yl 4-bromo-benzene-1-sulfonate.
abstract: The title mol-ecule, C(22)H(17)BrN(2)O(4)S, has a twisted U shape, the dihedral angle between the quinazolin-4-one and bromo-benzene 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, mol-ecules are connected into a three-dimensional architecture by C-H⋯O inter-actions, with the ketone O atom accepting two such bonds and a sulfonate O atom one.
