S, crystallized with two molecules (
A
and
B
) in the asymmetric unit. The terminal methyl group of the ethylsulfonamide moiety in molecule
B
is disordered over two sets of sites with an occupancy ratio of 0.61 (1):0.39 (1). Both molecules have L-shaped conformations. In molecule
A
, the dihedral angles between the benzene ring and its ethylsulfonamide and methylamide substituents are 83.5 (3) and 13.34 (18)°, respectively. Equivalent values for molecule
B
are 87.9 (3) and 6.32 (16)°, respectively. The C—S—N—C torsion angles are 66.5 (3)° for A and −64.4 (3)° for
B
, indicating similar twists about the S—N bonds, but in opposite senses. In the crystal, the
A
molecules are linked by pairs of N
s
—H⋯O (s = sulfonamide) hydrogen bonds, generating inversion dimers containing

(8) rings, while the
B
molecules are linked by N
s
—H⋯O hydrogen bonds into
C
(10) [100] chains. Finally, N
a
—H⋯O (a = amide) hydrogen bonds link the
A-
molecule dimers and
B
-molecule chains into a three-dimensional network.
