title: N-Acetyl-5-chloro-3-nitro-l-tyrosine ethyl ester.
abstract: The title compound, C(13)H(15)ClN(2)O(6), was synthesized by hypochlorous acid-mediated chlorination of N-acetyl-3-nitro-l-tyrosine ethyl ester. The OH group forms an intra-molecular O-H⋯O hydrogen bond to the nitro group and the N-H group forms an inter-molecular N-H⋯O hydrogen bonds to an amide O atom, linking the mol-ecules into chains along [100]. The crystal studied was a non-merohedral twin, with a 0.907 (4):0.093 (4) domain ratio.
