3-(2-Amino-ethyl)-2-(4-chloro-anilino)-quinazolin-4(3H)-one methanol 0.75-solvate.

In the asymmetric unit of the title compound, C(16)H(15)ClN(4)O·0.75CH(3)OH, there are two independent quinazolin-4(3H)-one mol-ecules and one and a half methanol mol-ecules. One of the methanol mol-ecules is disordered over two positions with equal occupancies. The dihedral angles between the quinazoline ring system and the chloro-benzene ring in the two quinazolin-4(3H)-one mol-ecules are essentially the same, at 39.83 (1) and 39.84 (1)°. Intra-molecular N-H⋯N and O-H⋯O, and inter-molecular N-H⋯O and N-H⋯N hydrogen bonds are observed. In addition, π-π stacking inter-actions, with centroid-to-centroid distances of 3.654 (1), 3.766 (1) and 3.767 (1) Å, and weak C-H⋯π inter-actions, are observed.
