S1. Comment

Substituted diphenyl sulfide derivatives are a class of compounds which display high in vitro and in vivo affinities for SERT [Please define], high selectivity for dopamine transporter sites (DAT) and partial selectivity over norepinephrine transporter sites (NET), and have been described as potent and selective SERT ligands.

The title compound, (I), was synthesized from 2-(2-methoxyphenylsulfanyl)benzoic chloride and 1-(2-methoxyphenyl)piperazine. The molecular structure of the title compound is illustrated in Fig. 1. In the molecule, the piperazine ring is in a normal chair conformation.

S2. Experimental

2-(2-Methoxyphenylsulfanyl)benzoic chloride (8 mmol), triethylamine (20 mmol) and 1-(2-methoxyphenyl)piperazine (8 mmol) in CHCl₃ (60 ml) were stirred at room temperature for 3–4.5 h. After cooling to room temperature, the mixture was washed with 2 M sodium hydroxide [Text missing] water. The organic layer was dried and evaporated in vacuo to dryness to give a sticky yellow oil, which solidified at room temperature. After recrystallization from 60% aqueous ethanol (50–70 ml), the title compound was obtained as a white crystalline solid. Crystals of (I) suitable for X-ray analysis were grown by slow evaporation of an absolute methanol solution at room temperature over 15 d.

S3. Refinement

All H atoms were positioned geometrically and refined as riding, with C—H distances in the range 0.93–0.98 Å and with U_iso(H) = 1.2 U_eq(C).

Special details

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.

Refinement. Refinement of F² against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F², conventional R-factors R are based on F, with F set to zero for negative F². The threshold expression of F² > σ(F²) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F² are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
