Abstract

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 R₂²(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.
