The title compound, C9H8N2O, is almost planar, with the C atom of the meth-oxy group deviating from the mean plane of the quinazoline ring system (r.m.s. deviation = 0.011 Å) by 0.068 (4) Å. In the crystal, mol-ecules form π-π stacks parallel to the b-axis direction [centroid-centroid separation = 3.5140 (18) Å], leading to a herringbone packing arrangement.
标题化合物C₉H₈N₂O几乎呈平面结构，甲氧基的C原子偏离喹唑啉环系统的平均平面（均方根偏差 = 0.011 Å）0.068 (4) Å。在晶体中，分子形成平行于b轴方向的π-π堆积[质心-质心间距 = 3.5140 (18) Å]，导致形成人字形堆积排列。
