Abstract

The molecule of the title compound, C23H20N4O, assumes a non-planar conformation in which the pyrazolone ring forms dihedral angles of 10.33 (11), 65.34 (11) and 63.52 (10)° with the three benzene rings. In the crystal, the molecules are linked by intermolecular N—H...N hydrogen bonds, generating chains parallel to the b axis. The secondary amino group is involved in an intramolecular N—H...O hydrogen bond.
