Source of material

6-Chloro-5-ethyluracil (1.75 g, 0.01 mol) and m-thiocresol (1.24 g, 0.01 mol) were added to a solution of potassium hydroxide (0.56 g, 0.01 mol), in ethanol (50 mL), and the mixture was heated under reflux for four hours. The solvent was then evaporated in vaccuo and the residue was treated with water (200 mL), filtered, washed with cold water, dried and crystallized from aqueous ethanol to yield 1.99 g (76%) of the title compound as colourless needles. M.P.: 452–454 K. Crystals suitable for X-ray diffraction were obtained by slow evaporation of an ethanolic solution at room temperature. 1H NMR (DMSO-d6, 250 MHz): δ 0.95 (t, 3H, CH2CH3, J = 7.4 Hz), 2.31 (s, 3H, CH3), 2.45 (q, 2H, CH2CH3, J = 7.4 Hz), 7.23–7.48 (m, 4H, Ar-H), 10.82 (s, 1H, NH), 11.22 (s, 1H, NH). 13C NMR (DMSO-d6, 62.9 MHz): δ 13.61 (CH2CH3), 19.74 (CH2CH3), 20.73 (CH3), 118.63 (Pyrimidine C-5), 126.97, 127.52, 128.20, 129.16, 130.66, 138.82 (Ar—C), 142.83 (Pyrimidine C-2), 150.48 (Pyrimidine C-6), 163.03 (Pyrimidine C-4). ESI-MS, m/z: 261.2 (M-H).

Experimental details

Cell refinement and data reduction were carried out by Bruker SAINT and SHELXS-97 [16, 17]. The nitrogen bonded hydrogen atoms were refined freely; all others were idealizes and refined using a riding model (AFIX43, AFIX23 or AFIX137 option of the SHELX program [16].

Discussion

The pyrimidine-2,4(1H,3H-dione (uracil) nucleus is a major pharmacophore in many chemotherapeutic agents. The chemotherapeutic efficacy of pyrimidine-related derivatives is related to their ability to inhibit vital enzymes responsible for DNA biosynthesis including dihydrofolate reductase (DHFR), thymidylate synthetase (TSase), thymidine phosphorylase (TPase) and reverse transcriptase (RTase). 1-[2-(Hydroxyethoxy)methyl]-6-(phenylthio)thymine (HEPT) and its derivatives have long been known for their potent activity against human immunodeficiency viruses (HIV) [17]. In addition, numerous pyrimidine-related derivatives displayed marked activities against herpes simplex viruses (HSV) [8], and hepatitis B viruses (HBV) [9]. Moreover, potent anticancer [10, 11] and antimicrobial activities [1215] were observed among several pyrimidine-2,4-dione derivatives. In the present investigation, we report the crystal structure of the title compound, which was proved to exhibit marked anti-HIV-1 activity [7].

The asymmetric unit of the crystal structure of title compound contains one molecule. There are two aromatic ring systems in title molecule: the tolyl ring (C7—C12) and the pyrimidine ring (C3/C4/N1/C5/N2/C6) attached to the sulphur atoms. The of these rings planes are almost perpendicular and make a dihedral angle of 88.94(3)°. The molecules packing in the crystal structure is stabilized via three intermolecular hydrogen bonds, of which the O1 and O2 act as hydrogen bond acceptors and N1, N2 and C9 act as hydrogen bond donors. The distance of the interactions between the N2—H1N2⋯O2i, N1—H1N1⋯O1ii and C9—H9A⋯O1iii are 2.04(2), 2.00(2) and 2.47 Å, respectively, and the angles are 163(2), 169.7(19) and 146.0°, respectively. Symmetry codes: (i) -x+1, -y+1, -z+1; (ii) -x, -y, -z+1; (iii) x+1, y+1, z.
