N2 - In the title compound, C 18H 13BrN 4O 3S 3, the tetra-hydro-pyridine ring adopts a half-chair conformation with the central methylene-C atom of the NCH 2CH 2 unit at the flap. The dihedral angles between the tetra-hydro-pyridine 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.
