organic compounds
The title compound, C9H10Br2N2O3, was synthesized by condensation of β-alanine methyl ester with 4,5-dibromo-1-methyl-2-trichloroacetylpyrrole at room temperature, followed by saponification and acidification. In the crystal structure, intermolecular N—HO and O—HO hydrogen-bond interactions link the molecules into extended ribbons parallel to the a axis.
