In the title compound, C(27)H(30)N(3)O(3)P, the pyrazole ring is essentially planar [maximum deviation = 0.002 (2) Å] and it forms dihedral angles of 9.3 (1) and 40.2 (1)°, respectively, with the phenyl rings attached to the N and C atoms. In the crystal, pairs of centrosymmetrically related mol-ecules are linked into dimers by N-H⋯O hydrogen bonds.
