The crystal structure of (

Two independent N—H⋯O hydrogen bonds link all of the mol­ecules into a continuous three-dimensional framework structure. The quinazoline ring adopts an envelope conformation with the 2,5-di­meth­oxy­phenyl­unit occupying a quasi-axial site.
In the title compound, C61H15ClN2O3, the heterocyclic ring adopts an envelope conformation, folded across the N⋯N line, with the 2,5-di­meth­oxy­phenyl unit occupying a quasi-axial site. There are two N—H⋯O hydrogen bonds in the structure: one hydrogen bond links mol­ecules related by a 41 screw axis to form a C(6) chain, and the other links inversion-related pairs of mol­ecules to form an R 2 2(8) ring. The ring motif links all of the chains into a continuous three-dimensional framework structure. Comparisons are made with the structures of some related compounds.
