In the crystal structure of the title compound, C25H30N2O4, the steric size of the tert-butyl group causes the 3,5-dimethylphenyl ring to adopt a transoid geometry with respect to the N—C(O) bond. The six-membered heterocyclic ring is disordered over two sites, with occupancies of 0.553 (4) and 0.447 (4). Intramolecular C—H⋯O interactions are present. In the crystal, molecules are linked by intermolecular N—H⋯O and C—H⋯O hydrogen bonds.
