2-%28AMINOMETHYL%29-5-METHYLPYRAZINE is 2- (aminomethyl) -5 -methylpyrazine, which is an organic compound. According to its physical properties, under normal temperature and pressure, it is often colorless to light yellow liquid. It has a specific odor or a weak pungent odor.
In terms of solubility, it exhibits good solubility in organic solvents, such as ethanol, ether, etc. Because the molecular structure of the compound contains specific functional groups, it can generate suitable interactions with organic solvent molecules, such as van der Waals force, hydrogen bond, etc., so it can be well dispersed in it. However, the solubility in water is relatively limited, because the polarity of the molecule as a whole is not well matched with the polarity of water.
When it comes to the boiling point, the boiling point of the substance is within a certain range, which is determined by the intermolecular forces. The van der Waals forces between molecules and the possible hydrogen bonds make it necessary for the molecules to obtain enough energy to overcome the attractive forces between them and transform from liquid to gaseous state to determine their boiling point value. As for the melting point, it is also restricted by the regularity of the arrangement of molecules and the interaction force. If the molecular arrangement is regular and the interaction force is strong, the melting point is relatively high; otherwise, it is low. The molecular structure characteristics of 2 - (aminomethyl) -5 -methylpyrazine make its melting point in the corresponding range. < Br >

2-%28AMINOMETHYL%29-5-METHYLPYRAZINE is 2- (aminomethyl) -5 -methylpyrazine, and its preparation method is as follows:
First, by using 2-chloromethyl-5-methylpyrazine as the starting material. This starting material is heated with ammonia under suitable reaction conditions, such as in a suitable solvent (such as alcohol, ethanol, etc.), and a certain reaction temperature (such as 50-100 ° C) is controlled. Nucleophilic substitution reaction is carried out. 2-chloromethyl-5-methylpyrazine chloromethyl is active, ammonia attacks chloromethyl as a nucleophilic agent, and the chlorine atoms leave, thereby generating 2 - (aminomethyl) -5 -methylpyrazine. This reaction requires attention to the amount of ammonia, generally in excess to ensure that the reaction is fully carried out, and at the same time, the reaction temperature should be controlled to avoid excessive temperature leading to side reactions, such as the formation of multi-substituted products.
Second, 2-cyano-5-methylpyrazine is used as the raw material. In the presence of a catalyst, such as Raney nickel, the hydrogenation reduction reaction is carried out in a hydrogen atmosphere. This reaction is usually in an appropriate solvent (such as ethyl acetate, etc.), controlled temperature (such as 30-80 ° C) and hydrogen pressure (such as 1-5 atm), and the cyano group is gradually reduced to aminomethyl to obtain the target product 2 - (aminomethyl) -5 -methylpyrazine. This method requires attention to the activity and stability of the catalyst, and at the same time requires the sealing of the reaction device to ensure the stability of the hydrogen atmosphere and prevent the safety hazard caused by hydrogen leakage.
Third, the construction method of nitrogen-containing heterocycles is used. Through suitable organic synthesis reagents, such as pyrazine precursors containing amino groups and methyl groups, under specific reaction conditions, such as in the presence of basic conditions (such as sodium hydroxide, potassium carbonate and other basic reagents), 2 - (aminomethyl) -5 - methylpyrazine structures are constructed by cyclization reaction. This method requires precise control of the proportion of reaction reagents and reaction conditions to ensure that the cyclization reaction proceeds in the direction of the target product and avoids the generation of other by-products with similar structures.
