The asymmetric unit of the title compound, C30H46N6O4, contains one half-mol-ecule. The C(benzene)-C(CH2)-N-C(-Me) torsion angle is -79.89 (13)° suggesting a synclinal orientation of the nitro-benzene ring with respect to the macrocycle. The conformation of the macrocycle is stabilized by intra-molecular N-H⋯N hydrogen bonds.
