Two independent mol-ecules comprise the asymmetric unit in the title thio-carbamide derivative, C(10)H(13)NOS. These differ in the relative orientations of terminal ethyl groups [C-C-C-O torsion angles = -66.95 (13) and 55.92 (13)°, respectively]. The phenyl ring is twisted out of the plane of the central residue [C(q)-N-C(ph)-C(ph) = -146.20 (12) and -144.15 (12)°, respectively; q = quaternary and ph = phen-yl]. The independent mol-ecules are linked into a dimeric aggregate by N-H⋯S hydrogen bonds and an eight-membered thio-amide {⋯H-N-C=S}(2) synthon.
