title: Methyl 4-(butyrylamino)-5-methyl-2-nitro-benzoate.
abstract: The title compound, C(13)H(16)N(2)O(5), is useful as an inter-mediate in the field of agrochemicals. Intra-molecular C-H⋯O hydrogen bonds result in the formation of one six- and one five-membered nearly planar ring; the six-membered ring is also nearly coplanar with the adjacent benzene ring. In the crystal structure, inter-molecular C-H⋯O hydrogen bonds link the mol-ecules.
