The title_compound, C₁₉H₂₇N₃0₂, crystallizes in space
group P1 with two molecules in the asymmetric unit
which differ slightly in conformation. Intermolecular
N--H...N and C--H...O interactions generate a
hydrogen-bonded ring system between the alternating
molecules, graph set R²₂(16), with N...N distances
of 3.021 (3) and 3.041 (3)Å, and C...O distances of
3.219(3) and 3.296(3)Å along the hydrogen-bonded
chains.
