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 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 R22(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.
1. 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).
2. 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 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)°.
In compound (I), the intramolecular N1—H1A⋯N2 hydrogen bond (Table 1) generates an S(7) ring motif, as shown in Fig. 1. Amine atoms N4 and N5 attached to the pyrimidine ring deviate by 0.018 (3) and 0.060 (3) Å, respectively. The chlorine atom Cl1 attached to the benzene ring deviates by 0.058 (1) Å.
In compound (II), intramolecular N5—H5⋯N4 and N10—H10⋯N9 hydrogen bonds (Table 2 and Fig. 2) in molecules A and B, respectively, also generate S(7) ring motifs. In molecule A, the amine group atoms N1 and N2 attached to the pyrimidine ring deviate by 0.006 (3) and 0.004 (3) Å, respectively. The chlorine atom Cl1 attached to the benzene ring deviates by 0.013 (1) Å. In molecule B, the amine group atoms N6 and N7 attached to the pyrimidine ring deviate by −0.003 (3) and 0.050 (3) Å, respectively. Atom Cl2 attached to the benzene ring deviates by 0.074 (1) Å.

3. Supramolecular features
In the crystal of (I), molecules are linked by pairs of N—H⋯N hydrogen bonds, forming inversion dimers with an R22(8) ring motif (Table 1 and Fig. 4). The dimers are linked by via bifurcated N—H⋯O and C—H⋯O hydrogen bonds, forming corrugated layers parallel to the ac plane (Table 1 and Fig. 5).
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). Likewise the B molecules are also linked by N—H⋯O and N—H⋯Cl hydrogen bonds, forming layers parallel to (100). The parallel layers of A and layers of B molecules are linked via N—H⋯N hydrogen bonds, forming a three-dimensional structure (Table 2 and Fig. 6).
4. 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.
5. Synthesis and crystallization
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.

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.
6. Refinement
Crystal data, data collection and structure . 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 Uiso(H) = 1.2Ueq(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. |

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. |
