Source of material

The compound was prepared and characterised as described in the literature [5]. Crystals for the crystallographic study were obtained from the slow evaporation of a very dilute methanol solution.

Experimental details

The C-bound H atoms were geometrically placed (C—H = 0.98−0.99 Å) and refined as riding with Uiso(H) = 1.2–1.5Ueq(C). The N-bound hydrogen atoms were located in difference Fourier maps, but were refined with a distance restraint of N—H = 0.88 ± 0.01 Å, and with unconstrained Uiso(H).

Discussion

The 5-aza-7-deaza-isostere (imidazo[1,2-a][1,3,5]triazine) of the purine system is an important scaffold for the construction of various drugs. Such compounds have been developed as inhibitors for enzymes, e.g. focal adhesion kinase [6]. Further, these compounds display anti-viral activity [7], are agonists of opioid m-receptors [8] and function as ligands for adenosine receptors [9]. A hindrance to the embellishment of this class of compound has been the difficulty in their synthesis. Very recently, a new procedure for the synthesis of 5-aza-7-deaza-isosteres was developed, i.e. through the reaction of 2-aminoimidazoles, triethylorthoformate and cyanamide under microwave irradiation [5]. The title compound was one of the new compounds synthesised in the course of that study.

The title molecule is shown in the figure (70% displacement ellipsoids) and comprises a six- and five-membered fused ring system connected to the 4-methylphenyl group at C4. The r.m.s. deviation of the nine atoms of the imidazo-triazine group is 0.0218 Å with the maximum deviations being 0.0399(7) Å for the C2 atom and to the other side of the least-squares plane, 0.0273(7) Å for the C3 atom. The amino-N5 atom lies 0.1258(13) Å out of the plane in the direction of the C2 atom. There is a twist between this plane and that through the appended 4-methylphenyl group as seen in the dihedral angle of 12.39(4)° formed between them. The overall molecular geometry resembles that reported for the 4-methoxyphenyl derivative [5].

As anticipated, the molecular packing features a number of conventional hydrogen-bonding interactions. Thus, centrosymmetricaly related molecules associate via amine-N—H⋯N(triazine) hydrogen bonds and eight-membered {⋯HNCN}2 synthons [N5—H2n⋯N2: 2.066(11) Å and 179.6(17)° for symmetry operation 1−x, 2−y, 1−z]. The dimeric aggregates are connected into twisted, one-dimensional supramolecular chains, parallel to [1 0 1̄], via amine-H⋯amine-N—H⋯N(triazine) hydrogen bonds, involving the other amine-H and triazine-N atoms [N5—H1n⋯N1: 2.074(13) Å and 168.2(12)° for symmetry operation −1/2 + x, 3/2−y, −1/2 + z].
