The title compound, C(20)H(27)NOS, was obtained from the corresponding O-thio-carbamate. The structure features a C=O bond distance of 1.209 (2) Å and an sp(3)-hybridized S atom [C-S-C = 101.66 (1)°]. The steric bulk of the 1-adamantyl substituent on the 2-position of the aromatic ring is reflected in the S-C-C-C torsion angle [-7.5 (3)°].
