چکیده
The title pyrrole derivative compound, C(12)H(17)NO(4), was synthesized from methyl 3-oxopenta-noate by a Knorr-type reaction and contains a pyrrole ring to which two diagonal alk-oxy-carbonyl groups and two diagonal alkyl substituents are attached. The methyl-carbonyl and ethyl-carbonyl substituents are approximately co-planar with the pyrrole ring, making dihedral angles of 5.64 (2) and 3.44 (1)°, respectively. In the crystal, adjacent mol-ecules are assembled by pairs of N-H⋯O hydrogen bonds into dimers in a head-to-head mode.
