title: Ethyl 4-butyl-amino-3-nitro-benzoate.
abstract: In the crystal structure of the title compound, C(13)H(18)N(2)O(4), the asymmetric unit consists of three crystallographically independent ethyl 4-butyl-amino-3-nitro-benzoate mol-ecules. There is an intra-molecular N-H⋯O hydrogen bond in each mol-ecule, which generates an S(6) ring motif. The structure is stabilized by inter-molecular N-H⋯O and C-H⋯O hydrogen bonds.
