In the title compound, C26H27BrN3O3P, the central pyrazole ring forms a dihedral angle of 71.7 (2)° with the bromo­phenyl ring. In the crystal, mol­ecules are linked by pairs of N—H⋯O hydrogen bonds, forming inversion dimers with R22(10) ring motifs. Four C atoms of the 3-phenyl ring are disordered over two sets of sites [site occupancies = 0.745 (6) and 0.225 (6)].
