Deskripsi
In the title compound, C20H22N2O2S, the central thienopyrimidine ring system is essentially planar, with a maximum displacement of 0.023 (2) Å. The attached cyclohexene ring is disordered over two possible conformations, with an occupancy ratio of 0.776 (12):0.224 (12). Neither intermolecular hydrogen-bonding interactions nor π–π stacking interactions are present in the crystal structure. The molecular conformation and crystal packing are stabilized by three intramolecular C—H...O hydrogen bonds and two C—H...π interactions.
