Abstract: In the title compound, C₁₇H₂₁N₃O₃S, the dihedral angle between the aromatic ring planes is 84.2 (2)°. The pendant ethyl groups of the -N(C₂H₅)₂ group are disordered over two sets of positions in a 0.84 (2):0.16 (2) ratio. The molecular conformation is stabilized by an intramolecular O-HN hydrogen bond, and intermolecular N-HO bonds lead to [010] chains in the crystal structure.
