✦ Synopsis

In the title compound, C~19~H~27~N~3~OS, the central thienopyrimidine ring system is essentially planar. The cyclohexene ring adopts a half-chair conformation, while the piperidine ring is in a standard chair conformation. There is an intramolecular C—H...O hydrogen bond, which stabilizes the molecular structure. The crystal packing is stabilized by C—H...π interactions.
