In the title compound, C43H34N2O2S, the six-membered piperidine ring adopts a half-chair conformation. The five-membered thia­zole ring adopts a slightly twisted envelope conformation and the pyrrole ring adopts an envelope conformation; in each case, the C atom linking the rings is the flap atom. The mol­ecular structure features inter- and intra­molecular C—H⋯O inter­actions. Furthermore, the crystal packing is stabilized by four inter­molecular C—H⋯π inter­actions.
