title: 2,3-Di-methyl-quinazolin-4(3H)-one.
abstract: The non-H atoms of the title mol-ecule, C10H10N2O, are essentially coplanar, with a maximum deviation of 0.046 (4) Å for the O atom. In the crystal, mol-ecules are linked by weak C-H⋯O hydrogen bonds, forming chains along [010]. In addtion, weak C-H⋯π inter-actions and π-π stacking inter-actions between benzene and pyrimidine rings, with a centroid-centroid distance of 3.730 (3) Å, link the chains, forming a two-dimensional network parallel to (001).
