In the title compound, C(8)H(9)ClN(2)O(3)S, the benzene ring makes a dihedral angle of 4.1 (9)degrees with the amido -NHCO- plane including the major occupancy component of the carbonyl O atom [19 (4)degrees for the minor component]. An intramolecular C-H center dot center dot center dot O interaction occurs. The O atom of the carbonyl group is disordered over two positions with site-occupancy factors of 0.67 (11) and 0.33 (11). Intermolecular N-H center dot center dot center dot O hydrogen bonds help to stabilize the crystal structure.
