Abstract: In the title compound, C17H25N3O2S, the terminal and central amide groups are, respectively, twisted and coplanar with the attached benzene ring [O-C-C-C torsion angles = 22.7 (3) and 5.4 (3)°]. In the central part of the mol­ecule, the amide and thio­amide residues are approximately perpendicular [C-N-C-S torsion angle = -104.98 (18)°]. Supra­molecular layers with a zigzag topology are formed in the crystal packing by N-H...O, N-H...S and C-H...O inter­actions; these stack along c, being separated by hydro­phobic inter­actions.
