title: 2-(4-Chloro-N-{2-[(1H-pyrrol-2-yl)carbon-yloxy]eth-yl}anilino)ethyl 1H-pyrrole-2-carboxyl-ate.
abstract: In the title mol-ecule, C(20)H(20)ClN(3)O(4), both the pyrrole N-H groups adopt a syn conformation with respect to the carbonyl groups. In the crystal, inter-molecular N-H⋯O hydrogen bonds link the mol-ecules into layers parallel to (102).
