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 = 0.044â à ) and is essentially orthogonal to both the 2-tolyl ring [dihedral angle = 89.51â (8)°] and to the ester group [the C-O-C-C torsion angle = -103.69â (16)°]. The carboxyl-ate group is almost coplanar with the benzene ring to which it is attached [O-C-C-C torsion angle = -4.7â (2)°]. The 2-tolyl ring system is disordered over two orientations in a 0.871â (3):0.129â (3) ratio. In the crystal, mol-ecules are consolidated into a three-dimensional architecture by C-Hâ¯Cl, C-Hâ¯O, C-Hâ¯N, C-Hâ¯Ï and Ï-Ï inter-actions [inter-centroid distances = 3.6443â (9) and 3.8557â (11)â à ].
