Abstract
In the title molecule, C26H23Cl2NO3S, the tetrahydropyridine ring adopts a half-chair conformation. Intramolecular O-H center dot center dot center dot O hydrogen bonding generates an S(6) ring motif. Intermolecular N-H center dot center dot center dot Cl, C-H center dot center dot center dot Cl and C-H center dot center dot center dot S hydrogen bonding generates primary graph-set motifs C(8), C(11) and C(6), respectively. No significant pi-pi interactions exist in the crystal structure.
