2-Chloro-N-{5-[(4R,5R,10S)-dehydro-abiet-4-yl]-1,3,4-thia-diazol-2-yl}benzamide
Abstract:
There are two independent mol-ecules in the asymmetric unit of the title compound, C(28)H(32)ClN(3)OS (systematic name: 2-chloro-N-{5-[(1R,4aS,10aR)-7-isopropyl-1,4a-dimethyl-1,2,3,4,4a,9,10,10a-octa-hydro-phenanthren-1-yl]-1,3,4-thia-diazol-2-yl}benzamide). In each mol-ecule, the cyclo-hexyl ring attached to the thia-diazole fragment adopts a classic chair conformation with two of its two methyl groups in the axial positions. In the crystal, pairs of inter-molecular N-H⋯N hydrogen bonds link the mol-ecules into centrosymmetric dimers, which are further linked via C-H⋯π inter-actions.

Nomenclature of Aromatic Compounds with Multiple Substituents
For disubstituted benzene derivatives, with two groups attached to the benzene ring, three constitutional isomers are possible. For example, consider dimethyl benzene, often called xylene, where the second methyl group can be substituted at the second, third, or fourth carbon. The relative position of the substituents is represented by prefixes ortho, meta, or...
