(2E)-2-(2,4-Dichloro­phenyl­sulfon­yl)-3-(4-methyl­anilino)-3-(methyl­sulfan­yl)acrylonitrile

Abstract

The title compound, C17H14Cl2N2O2S2, and the 3-methoxy­anilino analogue reported in the preceding paper have been used as starting materials to develop benzothia­zine derivatives with anti­malarial activity. The mol­ecule displays an E (trans) configuration about the central double bond. Due to conjugation in the C=C—C N group, the putative single bond shows a significant shortening [1.418 (3) Å]. The mol­ecule has a six-membered ring involving an intra­molecular N—H(...)O(sulfon­yl) bond, which is an example of resonance-assisted hydrogen bonding. In the crystal structure, bonds of the C—H(...)O(sulfon­yl) and C—H(...)N(cyano) types form double layers of mol­ecules parallel to (An external file that holds a picture, illustration, etc.
Object name is e-64-0o983-efi1.jpg01). Within these layers there are π–π inter­actions between benzene rings of pairs of centrosymmetrically related mol­ecules, with distances of 3.7969 (12) Å between centroids. C—H(...)π interactions are also present.

Comment

The exploration of simple molecules with different functionalities for the synthesis of heterocycles is a worthwhile contribution to the chemistry of these compounds. The title compound (II), and the 3''-methoxy analogue (I) [see previous paper: Capparelli et al., 2008)], and similar derivatives, have been used as effective synthons in the syntheses of some 1H-pyrrole-2,5-diones (Tominaga et al., 2002), pyrimidine derivatives (Tominaga et al., 1989) and 4H-1,4-benzothiazine-1,1-dioxides (Charris et al., 2005). We used (I) and (II) as starting materials to develop benzothiazine derivatives with antimalarial activity (Charris et al., 2007; Barazarte et al., 2008).

The X-ray structure determination showed that there is one molecule per asymmetric unit (Fig. 1), which displays E (trans) configuration about the C2═C3 double bond. A search of the Cambridge Structural Database (version 5.29, updated Jan 2008) (Allen, 2002) produced no structures with the same central fragment (i.e. excluding the phenyl rings) of (II) for proper comparison, but a search for the more restricted fragment X—C(CN)═C(SMe)-N(H)—Y gave three comparable structures, viz. TAKDOZ (Krivokolysko et al., 2002), AJULUM (Kennard et al., 2003) and DALVES (Song et al., 2005). Due to conjugation in the C3═C2—C1[equivalent]N1 moiety, the putative single bond C2—C1 (1.418 (3) Å) shows a significant shortening, similar to the range 1.415 (7)–1.437 (4) Å observed in the aforementioned structures. Bond lengths (see Supplementary Materials) are in good agreement with the expected values (Allen et al., 1987). Within experimental error (i.e. 3 e.s.d.'s) all of the corresponding bond angles and most of the bond lengths and are equal in (I) and (II).

Aside from the σ-bonded (i.e. free rotating) phenyl and SMe groups, the molecules of (I) and (II) display a significant difference in the rigid moieties formed by the double bonds C2═C3 and their neighboring atoms (S1, C1, S2, N2). The planes defined by S1—C2—C1 and N2—C3—S2 make dihedral angles of 17.08 (17)° in (I) and 11.2 (3)° in (II), but they are twisted about C2═ C3 in different directions (Fig. 2), probably due to packing forces.

As in (I), the title compound displays a six-membered ring involving an intramolecular N—H···O(sulfonyl) bond (Table 1), which is an example of resonance-assisted hydrogen bonding (RAHB) (Gilli et al., 1989), as suggested by the ring bond lengths. Comparison with AJULUM and DALVES, which display similar rings [with N—H···O(carbonyl) and N—H···O(carboxyl) bonds respectively] and TAKDOZ, which does not have RAHB, reveal lengthenings of the C═C distances [AJULUM, 1.371 (2) Å; DALVES, 1.386 (7) Å; TAKDOZ, 1.345 (4) Å] and shortenings of the C—N bonds [AJULUM, 1.360 (2) Å; DALVES, 1.333 (6) Å; TAKDOZ, 1.404 (4) Å]. On the other hand, the bond length of S1═O2, involved in RAHB, (1.4345 (15) Å) is nearly identical to the S1═ O1 (1.4343 (15) Å). The molecular geometry also allows for a possible C4—H4b···Cg2 intramolecular interaction (Cg2: see below).

In the crystal structure (Fig. 3) bonds of the C—H···O(sulfonyl) and C—H···N(cyano) type form double layers of molecules parallel to (-1 0 1). Within these layers there are π-π interactions between phenyl rings of pairs of centrosymmetrically related molecules, with Cg1···Cg1(-x, 1 - y, -z), 3.7969 (12) Å (Cgm: centroid of ring Cm1—Cm6, m = 1, 2).

Experimental

To a solution of 2,4-dichlorobenzenosulfonylacetonitrile (1.50 g, 6.1 mmol) and KOH (0.46 g, 8.1 mmol) in anhydrous dioxane (10 ml) at 0°C, was added dropwise the 4-methylphenylisothiocianate (0.91 g, 6.1 mmol) dissolved in anhydrous dioxane (3 ml). The resulting solution was stirred for 4 h at room temperature and then was added iodomethane (0.87 g, 6.1 mmol) and the mixture was stirred by 5 h at room temperature. The solvent was removed under reduced pressure and the residue was dissolved in dichloromethane (20 ml), washed with water, brine, dried over anhydrous sodium sulfate, filtered and concentrated to dryness. The solid was purified by recrystallization from ethanol. Yield: 1.91 g (74%). Crystals suitable for X-ray analysis were obtained during the recrystallization.

The IR spectrum was determined on a Shimadzu model 470 spectrophotometer. IR data [KBr pellets, ν (cm-1)]: 3264 (NH), 2192 (CN), 1341 (SO2), 1133 (SO2).

The 1H NMR spectrum was recorded using a Jeol Eclipse 270 MHz [CDCl3/TMS, δ (p.p.m.), atomic numbering as in Fig. 1]: 2.20 (s, 3H, SCH3), 2.37 (s, 3H, CH3), 7.13 (d, 2H, H22, H26; J: 8.3 Hz), 7.21 (d, 2H, H23, H25; J: 8.3 Hz), 7.46 (dd, 1H, H15; J: 8.6, 1.9 Hz), 7.56 (d, 1H, H13; J: 1.9 Hz), 8.14 (d, 1H, H16; J: 8.6 Hz), 9.90 (brs, 1H, NH).

The elemental analysis was performed on a Perkin Elmer 2400 CHN analyzer; results (%) were within ±0.4 of predicted values. Calculated for C17H14N2O2Cl2S2: C, 49.40; H, 3.41; N, 6.78. Found: C, 49.35; H, 3.40; N, 6.83.

The melting point (uncorrected) was measured with a Fischer-Johns micro hot-stage apparatus: 182–184 °C.

Refinement

Hydrogen atoms were placed in calculated positions using a riding atom model with fixed C—H distances [0.86 Å for N, 0.93 Å for C(sp2), 0.96 Å for C(sp3)] and Uiso = p Ueq(parent atom) [p = 1.2 for N and C(sp2), 1.5 for C(sp3)].

DELU restraints (Sheldrick, 2008) were applied to C1—C2 and S1—O2 bonds which (before restraints) had values of ΔU/σ = 6.00 Å and 5.13 Å, somewhat above the standard maximun (i.e. ΔU/σ≤ 5 Å, Spek, 1998) for the rigid-bond test (Hirshfeld, 1976).

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.
