Experimental

R factor = 0.024; wR factor = 0.066; data-to-parameter ratio = 14.9. In the title compound, C14H20N2O2S, the sulfonamide O atoms lie to one side of the benzene ring and the aminobicyclo-heptanyl to the other side [Car—S—N—C torsion angle = 57.93 (11); ar = aromatic]. An intramolecular N—H N hydrogen bond is formed. In the crystal, a supramolecular chain is formed along the b axis via N—H O and N—H N hydrogen bonds.
