In the title compound, C13H15ClN2O, there are two crystallographically independent but conformationally similar (E)-molecules in the asymmetric unit [dihedral angles between the phenyl ring and a common planar fragment of the 1,3-diazepane moiety = 47.34 (16) and 48.00 (16)°]. The seven-membered ring system adopts a chair conformation in both molecules. In the crystal, N-HO hydrogen bonds lead to chains extending along the b-axis direction.
