In the title compound, C39H36N2O4S, the piperidine ring adopts a twisted half-chair conformation. In the pyrrolothiazole fused-ring system, the pyrrole ring adopts an envelope conformation (with the C atom bound to the thiazole ring being the flap atom) and the thiazole ring also exhibits an envelope conformation (with the N atom bound to the pyrrole ring as the flap). The molecular structure features a weak intramolecular C-HO interaction. In the crystal, a C-HO interaction forms a linear chain along the diagonal of the ac plane, generating a C(14) graph-set motif. A weak C-H interaction also occurs.
