2-Chloro-N-{5-[(4R,5R,10S)-dehydroabiet-4-yl]-1,3,4-thiadiazol-2-yl}benzamide
Abstract
There are two independent molecules in the asymmetric unit of the title compound, C28H32ClN3OS (systematic name: 2-chloro-N-{5-[(1R,4aS,10aR)-7-isopropyl-1,4a-dimethyl-1,2,3,4,4a,9,10,10a-octahydrophenanthren-1-yl]-1,3,4-thiadiazol-2-yl}benzamide). In each molecule, the cyclohexyl ring attached to the thiadiazole fragment adopts a classic chair conformation with two of its two methyl groups in the axial positions. In the crystal, pairs of intermolecular N—H...N hydrogen bonds link the molecules into centrosymmetric dimers, which are further linked via C—H...π interactions.
