Crystal structures of N-(4-chloro­phen­yl)-2-[(4,6-di­amino­pyrimidin-2-yl)sulfan­yl]acetamide and N-(3-chloro­phen­yl)-2-[(4,6-di­amino­pyrimidin-2-yl)sulfan­yl]acetamide

Abstract

The title compounds, C12H12ClN5OS, (I), and C12H12ClN5OS, (II), are 2-[(di­amino­pyrimidin-2-yl)sulfan­yl]acetamides. Compound (II), crystallizes with two independent mol­ecules (A and B) in the asymmetric unit. In each of the mol­ecules, in both (I) and (II), an intra­molecular N—H(...)N hydrogen bond forms an S(7) ring motif. The pyrimidine ring is inclined to the benzene ring by 42.25 (14)° in (I), and by 59.70 (16) and 62.18 (15)° in mol­ecules A and B, respectively, of compound (II). In the crystal of (I), mol­ecules are linked by pairs of N—H(...)N hydrogen bonds, forming inversion dimers with an R 2 2(8) ring motif. The dimers are linked via bifurcated N—H(...)O and C—H(...)O hydrogen bonds, forming corrugated layers parallel to the ac plane. In the crystal of (II), the A mol­ecules are linked through N—H(...)O and N—H(...)Cl hydrogen bonds, forming layers parallel to (100). The B mol­ecules are also linked by N—H(...)O and N—H(...)Cl hydrogen bonds, also forming layers parallel to (100). The parallel layers of A and B mol­ecules are linked via N—H(...)N hydrogen bonds, forming a three-dimensional structure.

Chemical context  

Di­amino­pyrimidine derivatives are reported to be therapeutic agents towards anti-cancer activity, selectively inhibiting c-Fms kinase of M-CSF-dependent myeloid leukemia cells (Xu et al., 2010  ). They have also shown anti­bacterial activity (Kandeel et al., 1994  ), are potential anti­microbial (Holla et al., 2006  ) and anti-AIDS agents (Nogueras et al., 1993  ) and anti­viral agents (Hocková et al., 2003  , 2004  ) and have shown promise as immunosuppressants (Blumenkopf et al., 2002  ). In this connection, the title 2-[(4,6-di­amino­pyrimidin-2-yl)sulfan­yl] based analogues have been synthesized as anti­viral agents against NS2B/NS3 Dengue protease. We report herein on the syntheses and crystal structures of the title compounds, (I) and (II).

Structural commentary  

The mol­ecular structures of compounds (I) and (II) are shown in Figs. 1  and 2  , respectively. Compound (II) crystallizes with two independent mol­ecules (A and B) in the asymmetric unit, which have similar conformations (Fig. 3  ). The mol­ecules of both compounds are folded with the pyrimidine ring being inclined to the benzene ring by 42.25 (14)° in (I), and by 59.70 (16) and 62.18 (15)° in mol­ecules A and B, respectively, of compound (II). In compound (I), the N1—C7—C8—S1 torsion angle is 77.2 (3)°, while in mol­ecule A of compound (II), N5—C6—C5—S1 is 85.2 (3)°, and in mol­ecule B N10—C18—C17—S2 is 68.4 (3)°.

Database survey  

A search of the Cambridge Structural Database (Version 5.37, update May 2016; Groom et al., 2016  ) for 2-[(pyrimidine-2-yl)sulfan­yl]-N-phenyl­acetamide yielded five hits. Three of these involve (4,6-di­amino­pyrmidin-2-yl) groups. They include the 2-chloro­phenyl analogue, N-(2-chloro­phen­yl)-2-[(4,6-di­amino­pyrimidin-2-yl)sulfan­yl]acetamide (ARARUI; Subasri et al., 2016  ). Here the pyrimidine and benzene rings are inclined to one another by 67.84 (6)°, compared to 42.25 (14)° in (I), and 59.70 (16) and 62.18 (15)° in mol­ecules A and B, respectively, of compound (II). As in the title compounds, there is also an intra­molecular N—H(...)N hydrogen bond present, stabilizing the folded conformation of the mol­ecule.

Synthesis and crystallization  

Compound (I):

To a solution of 4,6-di­amino-pyrimidine-2-sulfanyl (0.5 g; 3.52 mmol) in 25 ml of ethanol, was added potassium hydroxide (0.2g; 3.52 mmol) and the mixture was refluxed for 30 min, after which 3.52 mmol of 2-chloro-N-(4-chloro­phen­yl)acetamide derivative was added and refluxed for 4 h. At the end of the reaction (monitored by TLC), the ethanol was evaporated in vacuo and cold water was added; the precipitate formed was filtered and dried to give compound (I) as a crystalline powder (yield 97%). Colourless block-like crystals were obtained from a solution in methanol and ethyl acetate (1:1) by slow evaporation of the solvents at room temperature.

Compound (II):

To a solution of 4,6-di­amino-pyrimidine-2-thiol (0.5 g; 3.52 mmol) in 25 ml of ethanol was added potassium hydroxide (0.2g; 3.52 mmol) and the mixture was refluxed for 30 min. Then 3.52 mmol of 2-chloro-N-(3-chloro­phen­yl)acetamide was added and refluxed for 3 h. At the end of the reaction (monitored by TLC), the ethanol was evaporated in vacuo and cold water was added and the precipitate formed was filtered and dried to give compound (II) as a crystalline powder (yield 92%). Colourless block-like crystals were obtained from a solution in methanol and ethyl acetate (2:1) by slow evaporation of the solvents at room temperature.

Refinement  

Crystal data, data collection and structure refinement details are summarized in Table 3  . For both (I) and (II), hydrogen atoms were placed in calculated positions and refined as riding: C—H = 0.93–0.97 Å and N—H = 0.86 Å, with U iso(H) = 1.2U eq(N,C).

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

(II) N-(3-Chlorophenyl)-2-[(4,6-diaminopyrimidin-2-yl)sulfanyl]acetamide .  Special details

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