The anti-inflammatory and cytoprotective tricyclic title compound, C21H18N2O2, also known as TBE-31, crystallizes with two nearly superimposable molecules in the asymmetric unit. In both molecules, the three ring systems conform to an envelope–chair–planar arrangement. The central ring, in a cyclo...
