N'-tert-Butyl-N'-(3,5-dimethyl-benzo-yl)-2,2-dimethyl-4-oxochroman-6-carbo-hydrazide.

In the crystal structure of the title compound, C(25)H(30)N(2)O(4), the steric size of the tert-butyl group causes the 3,5-dimethyl-phenyl 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). Intra-molecular C-H⋯O inter-actions are present. In the crystal, mol-ecules are linked by inter-molecular N-H⋯O and C-H⋯O hydrogen bonds.
