摘要

In the title mol­ecule, C11H13N3O, the propyl group is almost perpendicular to the quinazolin-4(3H)-one mean plane, making a dihedral angle of 88.98 (9)°. In the crystal, mol­ecules related by an inversion centre are paired via π–π overlap, indicated by the short distances of 3.616 (5) and 3.619 (5) Å between the centroids of the aromatic rings of neighbouring mol­ecules. Inter­molecular N—H⋯N and N—H⋯O hydrogen bonds form R66(30) rings and C(5) chains, respectively, generating a three-dimensional network. Weak C—H⋯O inter­actions are also observed.
