In the title compound, C20H22N5O+·Br·C2H6O, the tetra­hydro­pyrimidine ring of the bicyclic cation adopts a half-chair conformation with an equatorial orientation of the phenyl and methyl substituents. The amino group is nearly coplanar with the 1,2,4-triazole ring [interplanar angle = 4.08 (8)°] and has a slightly pyramidal configuration. The mean planes of the triazole ring and the benzene ring of the phenacyl group form a dihedral angle of 88.58 (7)°. In the crystal, N—H⋯Br, N—H⋯O and O—H⋯Br hydrogen bonds link the cations, anions and ethanol mol­ecules into layers parallel to the bc plane.

Comment top

In the last years much attention has been paid to the development of new methods for synthesis and investigation of properties of partially hydrogenated [1,2,4]triazolo[1,5-a]pyrimidines with various degree of saturation of pyrimidine ring (Chebanov et al., 2008; Chebanov et al., 2010; Gorobets et al., 2012). In large part, the reason for this is that partially hydrogenated [1,2,4]triazolo[1,5-a]pyrimidines are the polyfunctional compounds capable to react with various electrophiles (Desenko, 1995; Chernyshev et al., 2008b; Gorobets et al., 2012; Lipson et al., 2012). This capability can serve for the molecular design of triazolopyrimidine scaffold and construction of more complex heterocyclic systems. Thus, the 4,7-dihydro[1,2,4]triazolo[1,5-a]pyrimidines have received successful application for the synthesis of new polycondensed heterocycles (Desenko, 1995; Beck et al., 2011; Lipson et al., 2006; Sidorenko & Orlov, 2011). However, potential of 4,5,6,7-tetrahydro[1,2,4]triazolo[1,5-a]pyrimidines for synthesis of polycondensed heterocycles remain almost unexplored. We have assumed the possibility of application of the tetrahydrotriazolopyrimidines as new N,N-binucleophilic synthons for preparation of polycondensed heterocycles. Recently, by the example of reaction of 2-amino-substituted 4,5,6,7-tetrahydro[1,2,4]triazolo[1,5-a]pyrimidines with 3-chloropropanoic acid chloride, we have reported a simple method of preparation of 8-oxo-1,2,3,4,7,8,9,10-octahydro[1,2,4]triazolo[1,5 - a:4,3-a']dipyrimidin-5-ium chlorides (Sokolov et al., 2011). Continuing our work on the elaboration of new methods for synthesis of polycondensed heterocycles, we investigated the reaction of 2-amino-substituted 4,5,6,7-tetrahydro[1,2,4]triazolo[1,5-a]pyrimidines with α-bromoketones as potential source of imidazotriazolopyrimidines (the detailed results will be published later). The present article reports the molecular and crystal structures of compound 1, the product of reaction between 5-methyl-7-phenyl-4,5,6,7-tetrahydro[1,2,4]triazolo[1,5-a]pyrimidin-2-amine (2) and 2-bromo-1-phenylethanone (3) in acetonitrile (Fig. 1).

In accordance with the X-ray diffraction data (Fig. 2), the triazole ring (C1/N1/C2/N2/N3) is planar, with the mean deviations of the ring atoms from their least-squares plane being 0.014 (2) Å. In analogy with the previously described salts of C-amino-1,2,4-triazoles (Chernyshev et al., 2010; Matulkova et al., 2012) and quaternized derivatives of tetrahydrotriazolopyrimidines (Chernyshev et al., 2008a) the bonds C1—N3 (1.323 (2) Å) and C2—N2 (1.312 (2) Å) are shorter than the bonds C1—N1 (1.362 (2) Å) and C2—N1 (1.394 (2) Å). The atoms N4 and N5 adopt a trigonal pyramidal configuration (the sums of valence angles are 349.8° and 357.2°, correspondingly) and deviates from the triazole plane by only 0.005 (2) Å and -0.020 (2) Å, respectively. Conjugation between the unshared electron pairs of N4 and N5 with the π–system of the triazole fragment leads to a shortening of the bonds C1—N4 (1.337 (2) Å) and C2—N5 (1.347 (2) Å) relative to the standard length of a purely single Nsp2–Csp2 bond (1.43–1.45 Å) (Burke-Laing & Laing, 1976; Allen et al., 1987). The tetrahydropyrimidine ring (C1/N3/C3/C4/C5/N4) adopts distorted half-chair conformation which was observed in other tetrahydro[1,2,4]triazolo[1,5-a]pyrimidines (Desenko et al., 1994), the Cremer-Pople ring puckering coordinates (Cremer & Pople, 1975) calculated with the help of PLATON program (Spek, 2009) are: Q = 0.470 (2) Å, Θ = 132.5 (2)°, ϕ = 38.1 (3)°. The phenyl and methyl substituents have equatorial orientation. Bond lengths and angles in the phenacyl group are within the normal ranges. Carbonyl group is slightly noncoplanar to the benzene ring, torsion angle O1—C14—C15—C16 is 13.9 (3)°. Dihedral angle between the mean square planes of triazole cycle and carbonyl group (O1/C13/C14/C15) is 77.41 (8)°.

The title compound contains four acidic hydrogen atoms at the NH2, NH and OH groups which all participate in H-bonding. Three H-bonds are formed with the bromine anion and one with the oxygen atom of the hydroxyl group. However the carbonyl oxygen atom which is known to be a strong proton-acceptor is not involved in H-bonding. Four H-bonds listed in Table 1 leads to formation of H-bonded layers parallel to bc crystallographic plane. All the other intermolecular contacts correspond to the ordinary van-der-Waals interactions.

Refinement top

The hydrogen atoms of NH, NH2 and OH groups were found in difference Fourier synthesis and normalized to the standard X-ray value of 0.90 Å for NH and NH2 groups, and 0.85 Å for OH group. The H(C) atom positions were calculated. All the hydrogen atoms were refined in isotropic approximation in riding model with the Uiso(H) parameters equal to 1.5 Ueq(Ci), 1.2 Ueq(Cj), 1.2 Ueq(N), 1.5 Ueq(O) where Ueq(Ci) and Ueq(Cj) are the equivalent thermal parameters of the methyl carbon atoms and all the other carbon atoms, respectively, to which corresponding H atoms are bonded; Ueq(N) and Ueq(O) are the equivalent thermal parameters of the nitrogen and oxygen atoms, respectively, to which corresponding H atoms are bonded.

Geometry. All s.u.'s (except the s.u.'s in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell s.u.'s are taken into account individually in the estimation of s.u.'s in distances, angles and torsion angles; correlations between s.u.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell s.u.'s is used for estimating s.u.'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 > σ(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.
