摘要：
The title pyrrole derivative compound, C12H17NO4, was synthesized from methyl 3-oxopentanoate by a Knorr-type reaction and contains a pyrrole ring to which two diagonal alkoxycarbonyl groups and two diagonal alkyl substituents are attached. The methylcarbonyl and ethylcarbonyl substituents are approximately co-planar with the pyrrole ring, making dihedral angles of 5.64 (2) and 3.44 (1)degrees, respectively. In the crystal, adjacent molecules are assembled by pairs of N-H center dot center dot center dot O hydrogen bonds into dimers in a head-to-head mode.
