چکیده
The title compound, C(15)H(23)NO(2)S, contains cyclo-hexyl and ethyl substituents on the sulfonamide N atom and the cyclo-hexyl ring adopts a classic chair conformation. The dihedral angle between the benzene ring plane and the mean plane through the six atoms of the cyclo-hexyl ring is 59.92 (6)°. In the crystal structure, C-H⋯O hydrogen bonds link mol-ecules into sheets extending in the bc plane.
