In the title mol-ecule, C13H13N3O, the isoxazole ring is inclined to the benzimidazole ring at a dihedral angle of 69.28 (14)°. In the crystal, N-H⋯N hydrogen bonds between neighboring benzimidazole rings form chains along the a-axis direction. Hi

The conformation of the title compound, C18H18N4O, is partly determined by an intramolecular N—H...O hydrogen bond that imposes planarity on the central aminoethylidene-3-methylpyrazol-5-one segment of the molecule. In the crystal, N—H...O hydrog
