Ethyl 4-[3-(1H-imidazol-1-yl)propyl­amino]-3-nitro­benzoate

In the title compound, C(15)H(18)N(4)O(4), the 1H-imidazole ring forms a dihedral angle of 67.12 (8)° with the benzene ring. An S(6) ring motif is formed via an intra­molecular N—H⋯O hydrogen bond. In the crystal, neighbouring mol­ecules are linked by a pair of inter­molecular N—H⋯N hydrogen bonds, forming an inversion dimer. The dimers are further linked by a pair of C—H⋯O hydrogen bonds, leading to the formation of chain along [021]. A C—H⋯π inter­action involving the centroid of the benzene ring is also observed between the chains.
