ABSTRACT: The title mol-ecule, C(30)H(28)N(2)O(4), has crystallographic twofold rotation symmetry, with the pyrrole planes forming a dihedral angle of 40.49?(4)°. The pyrrole N-H donor and adjacent ester carbonyl acceptor form R(2) (2)(10) hydrogen-bonded rings about inversion centers, leading to chains of hydrogen-bonded mol-ecules along [001].
