In the title compound, C(23)H(17)ClN(2)O(3), the quinazoline fused-ring system, including the ring-bound carbonyl-O and methyl-C atoms, is close to being planar (r.m.s. deviation = 0.044 Å) and is essentially orthogonal to both the 2-tolyl ring [dihedral angle = 89.51 (8)°] and to the ester group [the C-O-C-C torsion angle = -103.69 (16)°]. The carboxyl-ate group is almost coplanar with the benzene ring to which it is attached [O-C-C-C torsion angle = -4.7 (2)°]. The 2-tolyl ring system is disordered over two orientations in a 0.871 (3):0.129 (3) ratio. In the crystal, mol-ecules are consolidated into a three-dimensional architecture by C-H⋯Cl, C-H⋯O, C-H⋯N, C-H⋯π and π-π inter-actions [inter-centroid distances = 3.6443 (9) and 3.8557 (11) Å].
在标题化合物C₂₃H₁₇ClN₂O₃中,喹唑啉稠环体系,包括环连接的羰基氧原子和甲基碳原子,接近平面结构(均方根偏差 = 0.044 Å),并且与2-甲苯基环[二面角 = 89.51 (8)°]和酯基[C-O-C-C扭转角 = -103.69 (16)°]基本正交。羧酸根基团与其连接的苯环几乎共平面[O-C-C-C扭转角 = -4.7 (2)°]。2-甲苯基环体系在两种取向上无序,比例为0.871 (3):0.129 (3)。在晶体中,分子通过C-H⋯Cl、C-H⋯O、C-H⋯N、C-H⋯π和π-π相互作用[质心间距 = 3.6443 (9) 和3.8557 (11) Å]巩固成三维结构。
