Abstract
The asymmetric unit of the title compound, C26H36N2O8, comprises two independent molecules. In each molecule, the two pyrrole rings are linked by a –CH2CH2– bridge, with dihedral angles between the two pyrrole rings of 14.5 (3) and 16.4 (3)° in the two molecules. Each pyrrole ring carries 2- and 5-methyl substituents and ethoxycarbonyl groups at the 3- and 5-positions.
