In the title compound, C31H34N2O4, the two pyrrole rings are bent around the central methylene C atom, making a dihedral angle of 64.83 (7)°. In the crystal, molecules are linked into dimers via N-HO=C hydrogen bonds. These dimers are packed through interactions between neighboring pyrrole rings with a separation between the mean planes of symmetry-related pyrrole rings of 3.61 (2) Å and a centroid-centroid distance of 4.33 Å. Parallel phenyl groups in neighboring dimers also exhibit efficient interactions, characterized by an interplane separation of 3.378 (8) Å and a centroid-centroid distance of 3.97 Å.
