Abstract: The title compound, C12H16Br2N2O3, synthesized by the condensation of L-leucine methyl ester with 4,5-dibromo-2-trichloroacetylpyrrole at room temperature, crystallizes with two independent molecules in the asymmetric unit. Intermolecular N-HO hydrogen bonds link the molecules into ribbons extending along the b axis.
