Abstract: In the title sulfonamide derivative, C11H10ClN3O2S, the dihedral angle between the pyridine rings is 46.85 (12)°. The N atom of the chloropyridine ring is anti to the N-H bond. In the crystal, molecules are linked through N-HN hydrogen bonds into zigzag chains parallel to  with a C(7) graph-set motif.
