A nimesulide intermediate

The two phenyl rings make a dihedral angle of 73.5(1)°, indicating the non-planarity of the molecule. The orientation of the methanesulfonanilide moiety with respect to the phenyl ring is given by the C-S-N-C torsion angle of -69.2(2)°. Molecules are linked into pairs by N-H...O hydrogen bonding over an inversion centre.
