Molecules of the title compound, C16H16N2O2, occupy special positions on the twofold rotation axes. The heterocyclic ring adopts a slightly twisted envelope conformation with one of the two junction carbon atoms as the flap. The mean planes through the two halves of the molecule form a dihedral angle of 72.01 (2)°. In the crystal, molecules are linked by pairs of C—H...O and N—H...C contacts into layers parallel to (100). H...H contacts make the largest contribution to the Hirshfeld surface (58.9%).
