The conformation of the title molecule, C 24 H 26 N 2 O 4 S, is influenced by intramolecular N-HÁ Á ÁN hydrogen bonding, andinteractions link the molecules into centrosymmetric dimers. The crystal packing is further stabilized by weak intermolecular C-HÁ Á ÁO hydrogen bonds.

In the title compound, C~20~H~15~ClN~4~, the two benzene rings form dihedral angles of 30.95 (9) and 70.69 (6)° with the triazole ring, and the dihedral angle between the triazole and the pyridine rings is 43.38 (8)°. Intermolecular C—H...N hydrogen bonds are observed in the crystal structure.
