There are two molecules in the asymmetric unit of title compound, C11H16BrNO3, which was obtained via the tandem Michael addition-elimination reaction of 3,4-dibromo-5-methoxyfuran-2(5H)-one and 4-methylpiperidine in the presence of potassium fluoride. The furanone rings are approximately planar [maximum atomic deviations of 0.026 (2) and 0.015 (2) Å, respectively]. The packing is stabilized by weak intermolecular C-HO and C-HBr interactions.
