The asymmetric unit of the title compound, C21H24N2O2, consists of two independent molecules differing primarily in the orientation of the ends of the hexyl substituent, the C—C—C—C torsion angles being 71.7 (3) and170.5 (2)°. In the crystal, each independent molecule forms a chain along the a-axis direction through a C—H...O hydrogen bond with one chain also including a C—H...π interaction. Paired N—H...O hydrogen bonds between independent molecules form ribbons with additional C—H...O hydrogen bonds and C—H...π(ring) interactions tying them into a three-dimensional structure.
