The title compound, C18H17N3O2, crystallizes with Z' = 2 in space group P2(1)/c, and the two independent molecules are approximate, but not exact, mirror images. The molecular-electronic structure is strongly polarized, and the molecules are linked by paired N-H...O hydrogen bonds [H...O = 2.00-2.23 Angstrom, N...O = 2.798 (3)-2.992 (3) Angstrom and N-H...O = 145-151degrees] into two independent C(4)C(6)[R-2(1)(6)] chains of rings, which are linked into sheets by a single aromatic pi-pi-stacking interaction.
