Abstract: Two independent molecules, A and B, comprise the asymmetric unit of the title compound, C21H18N2OS, with the difference in the angle of orientation between the naphthalene ring system and the mean plane of the cycloheptyl ring [16.13 (1) in A and 11.48 (5)° in B], being evident. The cycloheptyl ring adopts a distorted chair conformation in each molecule with r.m.s. deviations of 0.2345 (4) (A) and 0.2302 (4) Å (B). Intramolecular O-H...N hydrogen bonding generates planar six-membered S(6) loops with r.m.s. deviations of 0.0099 (1) (A) and 0.0286 (1) Å (B).
