Abstract top

The title compound, C19H13Cl2NO3S, is an N-arylsulfonyl derivative of 2-amino-5-chlorobenzophenone. The compound is biologically active and shows potential to be utilized as an inhibitor of CCR2 and CCR9 receptor functions. In the crystal structure, there is an intramolecular N-H...O hydrogen bond between the amide and carbonyl groups. The benzoyl and 4-chlorophenyl groups form intramolecular and intermolecular face-to-face contacts, with a dihedral angle of 10.6 (1)° between their mean planes in both cases, and centroid-centroid separations of 4.00 (1) and 4.25 (1) Å for the intra- and intermolecular interactions, respectively.

Comment top

The title compound was originally prepared to study its molecular structure by spectroscopy (Kolehmainen et al., 2003). The compound has a sulfone group showing strong electron acceptor capability and two S=O double bonds with ineffective conjugation properties with other double bonds. The compound has also shown a potential to be utilized as inhibitor of CCR2 (Basak et al., 2008) and CCR9 (Fleming et al., 2003) receptor functions. This potent antagonist can possibly be utilized in pharmaceutical compositions for treatment of CCR2 and CCR9 related diseases.

In the crystal, there is an intramolecular N—H···O hydrogen bond between the amide and carbonyl groups (Fig. 1). The benzoyl and 4-chlorophenyl groups form intramolecular (Fig. 2) and intermolecular face-to-face contacts (Fig. 3), with a dihedral angle of 10.6 (1)° between their mean planes in both cases, and a centroid-centroid separation of 4.00 (1) and 4.25 (1)Å for the intra- and intermolecular interactions, respectively.

Experimental top

The title compound was obtained by condensation of 2-amino-5-chlorobenzophenone and 4-chlorobenzenesulfonyl chloride according to a previously described method (Sternbach et al., 1962). The reaction product was purified by crystallization from ethanol. The spectroscopic characterization (NMR, IR) has previously been reported by us (Kolehmainen et al., 2003). The single-crystal suitable for X-ray determination was obtained by extremely slow evaporation of a CDCl3 solution in a NMR tube.

Refinement top

All H atoms were visible in electron density maps, but those bound to C were placed in idealized positions and allowed to ride on their parent atoms at C—H distances of 0.95 Å with Uiso(H) = 1.2Ueq(C). The position of the N—H proton was refined with the N—H distance restrained to 0.91 (2) Å and with Uiso(H) = 1.2Ueq(N).

Special details top

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.
