N-(2,4-Dinitro­phen­yl)dehydro­abietyl­amine

In the crystal structure of the title compound, C26H33N3O4, there are two crystallographically independent mol­ecules. The two cyclohexane rings are trans-fused; the ring neighboring the phenyl group is in a half-chair conformation and the other is in a chair conformation. The two nitro groups and the benzene ring of the dinitro­phenyl group are almost coplanar. Intra­molecular N—H⋯O hydrogen bonds and weak inter­molecular C—H⋯O hydrogen bonds are observed
