In the title compound, C18H13BrN4O3S3, the tetrahydropyridine ring adopts a half-chair conformation with the central methylene-C atom of the NCH2CH2 unit at the flap. The dihedral angles between the tetrahydropyridine ring and the pyridine and two thiophene rings are 69.34 (13) 5.66 (13) and 68.63 (13)', respectively, while the dihedral angle between the 1,3,4-oxadiazole and tetrahydropyridine rings is 54.76(13)'. The molecule is stabilized by an intramolecular C—H...N interaction. In the crystal, adjacent molecules are connected via bifurcated C—H...(N,O) hydrogen bonds, forming a chain along the b axis.
