Abstract: In the title compound, C₂₁H₂₂N₂O₂, the mean plane of the pyrazole ring makes dihedral angles of 18.80 (12) and 77.13 (5)°, respectively, with the mean planes of the phenyl and tert-butylbenzyl rings. The carboxylate group is inclined at 8.51 (14)° with respect to the pyrazole ring. The crystal structure displays intermolecular O-HO hydrogen bonding, generating centrosymmetric dimers.
