چکیده
The asymmetric unit of the title compound, C(17)H(19)NOS, contains two independent mol-ecules which differ in the dihedral angles between the five- and six-membered rings [12.52 (10) and 4.63 (11)°]. Weak inter-molecular C-H⋯O hydrogen bonds link the two independent mol-ecules into pseudocentrosymmetric dimers. In one mol-ecule, the O atom of the carbonyl group is disordered over two positions in a 0.699 (4):0.301 (4) ratio.
