In the title compound, C14H16ClNO2, the cyclohexyl ring has a chair conformation. The dihedral angle between the benzene ring and the mean plane of the four planar C atoms of the cyclohexyl ring is 45.2 (3)°. The two carbonyl groups are trans to one another, with an O=C-C=O torsion angle of -137.1 (3)°. In the crystal, molecules are linked by N-HO hydrogen bonds forming chains propagating along . A region of disordered electron density, situated near the unit-cell corners, was treated using the SQUEEZE routine in PLATON [Spek (2009). Acta Cryst. D65, 148-155]. It gave a solvent-accessible void of ca 400 Å3 for only 21 electrons. It is probably due to traces of the solvent of crystallization and was not taken into account during structure refinement.
