title: 4-(2H-1,3-Benzodioxol-5-yl)-1-(4-methyl-phenyl)-1H-pyrazol-5-amine.
abstract: In the title compound, C17H15N3O2, two independent mol-ecules (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 mol-ecule has an envelope conformation with the methyl-ene 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, supra-molecular zigzag chains along the b-axis direction arise as a result of N-H⋯N hydrogen bonding. These are consolidated into supra-molecular double chains via C-H⋯O and C-H⋯π inter-actions.
