Source of material

A mixture of 2-adamantanone (1.5 g, 0.01 mol) and pyridine-3-carbohydrazide (1.37 g, 0.01 mol), in ethanol (10 ml) was heated under reflux with stirring for 4 h and the resulted clear solution was then concentrated to half the original volume and allowed to stand at room temperature overnight. The precipitated crystalline solid was filtered, dried and recrystallized from aqueous ethanol to yield 1.78 g (66%) of the title compound (C16H19N3O) as colourless needle crystals. M.P.: 461–463 K (188–190 °C). Single crystals suitable for X-ray analysis were obtained by slow evaporation of a CHCl3:EtOH (1:2) solution at room temperature. 1H NMR (DMSO-d6, 500.13 MHz): δ 1.85–2.03 (m, 14H, Adamantane-H), 6.80 (s, 1H, NH), 7.75 (t, 1H, Pyridine-H, J = 5.6 Hz), 8.65–8.94 (m, 2H, Pyridine-H, J = 5.6 Hz), 9.01 (s, 1H, Pyridine-H). 13C NMR (DMSO-d6, 125.76 MHz): δ 28.57, 32.15, 36.12, 38.50, 40.03, 162.05 (Adamantane-C), 124.65, 134.75, 139.03, 148.05, 152.75 (Pyridine-C), 163.95 (C = O). ESI-MS, m/z: 269.2 (M+H)+.

Experimental details

Cell refinement and data reduction were carried out by Bruker SAINT and SHELXS-97 [21, 22]. The hydrogen atoms were placed geometrically using a riding model (AFIX 13, 23 or 43 option of the SHELX-2008 program [21]).

Discussion

The incorporation of an adamantyl moiety into several molecules results in compounds with relatively high lipophilicity, which in turn modify the biological availability of these molecules. Beyond increasing partition coefficient, the adamantyl group positively modulates the therapeutic index of many experimental compounds through a variety of mechanisms [1, 2]. Adamantane derivatives were early known for their diverse chemotherapeutic activities such as antiviral [39], anticancer [10] and antibacterial [1114] agents. In addition, several hydrazide and hydrazine derivatives were reported to possess marked antifungal [15, 16], antileishmanial [17, 18] and anticancer [19, 20] activities. In continuation to our ongoing interest in the structural and pharmacological properties of adamantane derivatives [8, 1113], we synthesized the title compound as potential and/or precursor to chemotherapeutic agent.

The asymmetric unit of the crystal structure of the title compound contains one molecule. The molecule is a functionalized hydrazine with 3-pyridinoyl and adamantyl substituents attached to the two hydrazine nitrogen atoms, N1 and N2. The molecules packing in the crystal structure is stabilized by four intermolecular hydrogen bonds, of which O1 and N1 act as hydrogen bond acceptors and N2, C1 and C13 act as hydrogen bond donors. The distance of the interactions between N2—H1N2⋯N1 is 2.35 (3) Å, C1—H1A⋯N1 is 2.51 Å, C1—H1A⋯O1 is 2.46 Å and C13—H13A⋯O1 is 2.46 Å and the angles are 162.0 (3)°, 159°, 135° and 156°, respectively.
