In the title compound, C17H15N3O2, two independent mol­ecules (A and B) comprise the asymmetric unit. The major conformational difference arises in the relative orientation of the pyrazole ring amine and dioxole substituents which are anti in A and syn in B. The five-membered dioxole ring in each mol­ecule has an envelope conformation with the methyl­ene C atom as the flap. The mean plane through the benzodioxole and benzene groups make dihedral angles of 31.67 (8) and 68.22 (9)°, respectively, with the pyrazole ring in A; the equivalent values for B are 47.18 (7) and 49.08 (9)°. In the crystal, supra­molecular zigzag chains along the b-axis direction arise as a result of N—H⋯N hydrogen bonding. These are consolidated into supra­molecular double chains via C—H⋯O and C—H⋯π inter­actions.
