In the title compound, C26H30ClN5O·CHCl3, the purine molecule consists of essentially planar benzene and purine ring systems [maximum deviation 0.010 (4) Å for both ring systems] forming a dihedral angle of 85.52 (9)°. Intermolecular N—H⋯N hydrogen bonds link adjacent molecules into centrosymmetric dimers. The structure also contains intermolecular C—H⋯O and C—H⋯N interactions. The benzene rings form offset face-to-face π–π stacking interactions with an interplanar distance of 3.541 (4) Å and a centroid-to-centroid distance of 4.022 (4) Å.

The title compound was prepared according to a slightly modified literature procedure (Fiorini & Abel, 1998). 2,6-Dichloro-9-(propan-2-yl)-9H-purine (0.53 mmol, 122.5 mg) and (1-adamantyl)-[4-(aminomethyl)phenyl]methanone hydrochloride (0.56 mmol, 170 mg) were dissolved in a mixture of DMF (2 ml) and triethylamine (1.06 mmol, 0.15 ml). The resulting solution was stirred under reflux for 2 h (the reaction progress was monitored by TLC). After this period, the mixture was diluted with water and extracted five times with 15 ml of diethyl ether. The combined organic layers were washed twice with brine and dried over sodium sulfate. The desired product was obtained by evaporation of the solvent in vacuum and purified by
(silica gel; petroleum ether/ethyl acetate, v/v 1:1) to give a colourless crystalline powder (210 mg, 86%, mp 190–192°C). The crystal used for data collection was acquired by evaporation from a chloroform solution at room temperature.Data collection: CrysAlis CCD (Oxford Diffraction, 2006); cell

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. |

Purine molecules substituted at C2, C6 and N9 are known as potential ATP-competitive inhibitors of cyclin-dependent kinases (key regulators of the cell division cycle) and due to this fact, they can show an anticancer activity (Legraverend & Grierson, 2006). The adamantane scaffold is often used in order to improve the biological properties of potential or known drugs and a number of compounds with various biological activity have been described, e.g. antitumor agents published by Long et al. (2007).
The asymmetric unit of the title compound (Fig. 1) consists of a trisubstituted purine molecule with trichloromethane solvent in the ratio of one to one. Both benzene and purine rings are essentially planar with maximum deviation from the best plane being 0.010 (4) Å for C19 of the purine ring and 0.010 (4) Å for C16 of the benzene ring. The dihedral angle between purine and benzene rings is 85.52 (9)°. The torsion angles C18/N1/C19/C22, C19/N1/C18/C15, N1/C18/C15/C16 and H24A/C24/N4/C21 are 173.42 (4), -79.52 (4), -36.80 (5) and -34.28 (5)° respectively. Adjacent molecules are linked into centrosymmetric pairs by intermolecular N1—H1A···N5i hydrogen bonds (Table 2, Fig. 2; symmetry code: (i) -x, 1 - y, 1 - z). The trichloromethane molecule forms intermolecular C—H···N and C—H···Cl interactions. Additional intermolecular interactions (Table 2) include C23—H23A···O1, C5—H5B···N3, C—H···Cl contacts and offset face-to-face π–π interactions with an interplanar distance of 3.541 (4) Å and a centroid–centroid distance of 4.022 (4) Å.
