2-Aminopyrazine (2-aminopyrazine, Aminopyrazine) is an organic compound with unique chemical properties.
It is basic, and the nitrogen atom in the guain amino group contains lone pairs of electrons, which can bind protons and form salts in acidic solutions. This property makes it act as a base in chemical reactions, neutralizing with acids.
2-aminopyrazine is aromatic, the pyrazine ring conforms to the Shocker rule, has a closed conjugate system, and the number of π electrons is 6, which makes it stable. And the aromaticity has a great influence on its chemical properties. For example, in the electrophilic substitution reaction, the pyrazine ring can stabilize the reaction intermediate, which is conducive to the reaction. < Br >
It can participate in the electrophilic substitution reaction. Because the amino group is the power supply group, the electron cloud density of the pyrazine ring will increase, especially the amino ortho and para-positions, and the electrophilic reagents are easy to attack these positions.

For 2-aminopyrazine, there are various ways to prepare it. One is to use pyrazine as a base to react with ammonia under suitable conditions. Among them, an appropriate catalyst, such as metal oxides, needs to be selected. In a high temperature and high pressure environment, the hydrogen atom on the ring of pyrazine is replaced by an amino group, so 2-aminopyrazine is obtained. In this process, the control of temperature is the key. If it is too high, side reactions will occur, and if it is too low, the reaction will be slow and the efficiency will be poor.
The second method is to conduct a condensation reaction between a nitrogen-containing compound and a substance with active functional groups. For example, when a compound containing an amino group and a pyrazine derivative containing a halogen atom are catalyzed by a base, the halogen atom and the amino group undergo a nucleophilic substitution reaction. The strength of the base and the ratio of the reactants will affect the yield and purity of the reaction. Fine regulation is required to make the reaction proceed smoothly in the direction of generating 2-aminopyrazine.
Furthermore, it can be obtained from other heterocyclic compounds through a series of conversions. First, the heterocyclic ring is opened or modified by a specific reaction, the amino-related group is introduced, and then the ring is closed to form the pyrazine ring and retain the amino group, so as to obtain 2-aminopyrazine. This path is more complicated, but it is also a feasible method under specific raw materials and conditions. In the process of preparation, separation and purification are also important, and impurities are often removed by recrystallization, column chromatography, etc., to obtain pure 2-aminopyrazine to meet the required quality.
