(Received 15 June 2009; accepted 19 June 2009; online 24 June 2009)

The asymmetric unit of the title compound, C25H30ClN5, consists of two mol­ecules with slightly different geometrical parameters. The dihedral angles between the purine and benzene rings are 39.54 (5) and 23.69 (5)° in the two mol­ecules. The adamantane cages consist of three fused cyclo­hexane rings in classical chair conformations, with C—C—C angles in the range 108 (2)–111 (2)°. In the crystal, mol­ecules are linked into dimers via two N—H⋯N hydrogen bonds.

Supporting information


Comment top

The published structure represents a typical member of a new trisubstituted purine series currently synthesized in our laboratory. These molecules belong to the family of purine derivatives that exhibit a wide range of biological activities. Purine based molecules with suitable substituents at the most active centers can present low-molecular-weight inhibitors of cyclin-dependent kinases playing a crucial role in the regulation of the cell division cycle (Hardcastle et al., 2002). A unique adamantane moiety is frequently linked into known medicaments or drug candidates with the aim to improve the biological properties of these structures, e.g. a novel potent hypoglycemic agent reported by Villhauer et al. (2003).

The title compound (Fig. 1) crystallizes with two geometrically slightly different molecules in the asymmetric unit that are linked into dimers by two N–H···N hydrogen bonds (Table 1). The dihedral angles between purine and benzene rings are 39.54 (5)° and 23.69 (5)°. The torsion angles describing the orientation of isopropyl, purine, benzene and adamantane moiety C22–N5–C23–H23A, C21–C18–N1–C15 and C17–C12–C11–C1 are -177.4 (2), 174.9 (2) and -94.6 (3)° respectively. The corresponding values of torsion angles for the second conformer are 144.0 (2), 173.9 (2) and -98.4 (2)° respectively.

Experimental top

The title compound was prepared according to a slightly modified literature procedure (Fiorini & Abel, 1998). 2,6-Dichloro-9-(propan-2-yl)-9H-purine (0.85 mmol, 196 mg) and 4-[(1-adamantyl)methyl]aniline hydrochloride (0.90 mmol, 250 mg) were dissolved in a mixture of DMF (2.5 ml) and triethylamine (1.70 mmol, 0.24 ml). The resulting solution was stirred at 363 K for required time (according to TLC). After the reaction was complete, the mixture was diluted with water and extracted with diethyl ether (5 times 15 ml). The connected organic layers were washed twice with brine and dried over sodium sulfate. The desired product was obtained by evaporation of the solvent in vacuum followed by purification of the crude product using column chromatography (silica gel; light petroleum/ethyl acetate (1:1 v/v) as a colorless crystalline powder (152 mg, 41%, mp 453–457 K). The single crystals suitable for X-ray analysis were grown by liquid diffusion (acetone/hexane, 1:3 v/v) at room temperature within 24 h.

Refinement top

Hydrogen atoms were positioned geometrically and refined as riding using standard SHELXTL facilities, with their Uiso set to either 1.2Ueq or 1.5Ueq (methyl) of their parent atoms.

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 > 2σ(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.
