The title compound, C(8)H(10)ClNO(5), was obtained via a tandem Michael addition-elimination reaction of 3,4-dichloro-5-meth-oxy-furan-2(5H)-one and glycine methyl ester in the presence of triethyl-amine. The mol-ecular structure contains an approximately planar [maximum atomic deviation = 0.010 (2) Å] five-membered furan-one ring. The crystal packing is stabilized by inter-molecular N-H⋯O and weak C-H⋯O hydrogen bonding.
