Abstract: The crystal structure of the title compound, C19H24N4O, has been determined in the monoclinic space group P21/c. The two pyrazole substituents are arranged trans to each other; the dihedral angle between them is 83.9 (1)°. There is an intramolecular hydrogen bond, with an O
N distance of 2.769 (4) Å, and an intermolecular hydrogen bond, with an O
N distance of 3.197 (4) Å.
