In the title compound, C15H21N3O2S, a short intramolecular N—H...O hydrogen bond generates an S(6) ring. The molecule is twisted with a dihedral angle between the benzene ring and the mean plane of the cyclohexyl ring being 58.90 (6)°. In the crystal, inversion dimers are formed with each molecule linked to the other by two N—H(H)...O hydrogen bonds to the same acceptor, generating R21(6) loops. A region of disordered electron density was corrected for using the SQUEEZE routine in PLATON [Spek (2015). Acta Cryst. C71, 9–18]. The given chemical formula and other crystal data do not take into account the unknown solvent molecule(s).
