The six-membered cyclohexene ring in the title compound, C17H19Cl2NOS2, adopts an with the C atom bearing the two methyl groups representing the flap. This atom deviates by 0.716 (3) Å from the plane passing through the other five atoms of the ring (r.m.s. deviation = 0.072 Å). The molecular conformation is stabilized by an intramolecular N—H⋯S hydrogen bond. The hydroxy group engages in intermolecular O—H⋯O hydrogen bonding with adjacent acceptor atoms to generate a zigzag chain running along the c axis.

To a solution of (2,4-dichlorophenylamino)-5,5-dimethyl-cyclohex-2-en-1-one (0.1 mol) in DMSO (20 ml) and sodium hydroxide (0.4 g) in water (1 ml), carbon disulfphide (0.3 mol) was added in the course of 30 minutes. The mixture was stirred for 20 min below 283 K, and then 2-bromoethanol (0.1 mol) was added drop wise at room temperature for 30 min. The reaction mixture was left for 24 h and then diluted with water (200 ml) and acidified with 10% hydrochloric acid. The resulting precipitate was collected by filtration, dried and purified on silica gel column (40% ethyl acetate in hexane) to give yellow crystal (34.5% yield; mp.424 K).
Carbon-bound H-atoms were placed in calculated positions (C—H 0.93 to 0.99 Å) and were included in the
in the riding model approximation, with U(H) set to 1.2 to 1.5U(C).The amino and hydroxy H-atoms were located in a difference Fourier map, and were refined with distance restraints of N–H 0.88±0.01 and O–H 0.84±0.01 Å; their isotropic displacement parameters were freely refined.
The final difference Fourier map had a large peak at 1 Å from S1, but was otherwise featureless.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
