Source of material
4-Formylbenzonitrile (10 mmol), pentane-2,4-dione (10 mmol), 5-aminotetrazole (10 mmol), 7.5 mL propane-1,2-diol and 2 mL water were added successively into a 25 mL reaction vessel, stirred well before the mixture was sealed in the vessel. The mixture was kept at 120 °C for 12 h before it was cooled to room temperature. The reaction solution was poured into 50 mL distilled water, stirred vigorously for 10 min, and then the solid of crude tetrazolopyrimidine was filtered out. Recrystallization from methanol and DMF gave the crystal product.
Experimental details
All the hydrogen atoms were calculated geometrically with C–H distances ranging from 0.93 to 0.98 A. Caryl–H = 0.93 Å, with Uiso(H) = 1.2Ueq(C). Cmethyl–H = 0.96 Å, with Uiso(H) = 1.5Ueq(C).
Comment
Pyrimidines are a very important class of substances in life activities [6]. They are widely present in the human body and other organisms. For example, among the five most common nitrogen-containing basic components in nucleic acids, there are three pyrimidine-containing structures. Pyrimidine compounds have received widespread attention because of their strong biological activities [7]. Medicines containing pyrimidine rings mainly focus on anti-tumor [8] and virus aspects [9], including very important anti-hepatitis B virus varieties and anti-HIV varieties [10]. Pesticides containing pyrimidine rings have excellent performance in the three major fields of weeding, insecticide and sterilization and even plant growth regulators [11].
Under hydrothermal and solvothermal conditions, with special physical and chemical properties of various solvents in the subcritical or supercritical state [12], the activity of the reactants was greatly enhanced, the required reaction temperature was greatly reduced, the development of low-temperature synthetic chemistry was promoted, new chemical reactions were discovered.
In the title molecule, C14H12N6O, all bond lengths are in normal ranges [13], [14]. The plane of the tetrazole ring forms dihedral angles of 77.56(9)° with the phenyl ring. The pyrimidine ring is in a flattened boat conformation. In the crystal, N–H⋅⋅⋅N hydrogen bonds stabilize the molecular structure.
