【 摘 要 】

In the title compound, C20H19N3O4, the dihedral angles between the central pyrazole ring and the pendant phenyl and substituted benzene rings are 50.95 (8) and 3.25 (12)°, respectively, and an intramolecular C—H...O link generates an S(6) ring. The benzodioxolyl ring adopts a shallow envelope conformation with the methylene C atom as the flap. In the crystal, the molecules are linked by non-classical C—H...O interactions, which generate a three-dimensional network. Solvent-accessible voids run down the c-axis direction and the residual electron density in these voids was modelled during the refinement process using the SQUEEZE algorithm [Spek (2015).
