What is the synthesis method of 3- (Trifluoromethyl) -5,6,7,8-tetrahydro- [1,2,4] triazolo [4,3-a] pyrazine hydrochloride?

To prepare 3- (trifluoromethyl) -5,6,7,8-tetrahydro- [1,2,4] triazolo [4,3-a] pyrazine hydrochloride, the method is as follows:
First, the appropriate starting material is obtained, usually the pyrazine-containing structure and the trifluoromethyl group that can be introduced and the triazole ring is preferably. If a pyrazine derivative with a specific substitution is used as a group, the derivative needs to have a reactive functional group in a suitable position, such as a halogen atom, an amino group, etc., for subsequent reactions to proceed.
In a reaction vessel, first contact the pyrazine derivative with the trifluoromethylating reagent. There are many commonly used trifluoromethylation reagents, such as Grignard reagents such as trifluoromethyl magnesium halide, or trifluoromethylsulfonyl chloride. The reaction conditions need to be carefully regulated, and temperature and solvent are all affected. Generally, polar aprotic solvents, such as N, N-dimethylformamide (DMF) or dimethyl sulfoxide (DMSO), are selected, and the temperature may be maintained at low temperature to room temperature, depending on the specific reagent activity. After trifluoromethylation, trifluoromethyl is introduced into the pyrazine structure.
Subsequently, a triazole ring is constructed. Nitrogen-containing reagents, such as sodium azide, are often used to react with pyrazine derivatives that have been introduced with trifluoromethyl. This reaction may require auxiliary catalysts, such as copper salts. Under suitable reaction conditions, after a cyclization reaction, a [1,2,4] triazolo [4,3-a] pyrazine skeleton is formed. At this time, the product is 3- (trifluoromethyl) -5,6,7,8-tetrahydro- [1,2,4] triazolo [4,3-a] pyrazine.
Finally, a salt-forming reaction is carried out to obtain hydrochloride. The above product is dissolved in a suitable solvent, such as ethanol or dichloromethane, and hydrogen chloride gas is introduced or hydrochloric acid solution is added. Control the reaction amount and conditions, and the product is fully divided into salts to obtain a pure 3- (trifluoromethyl) -5,6,7,8-tetrahydro- [1,2,4] triazolo [4,3-a] pyrazine hydrochloride. After separation and purification, such as recrystallization and column chromatography, high purity target products can be obtained.

And it needs to be stored separately from oxidants, acids, alkalis, etc., and must not be mixed. Because different chemicals may occasionally have violent chemical reactions, endangering safety.
Second, use with caution. When using, be sure to take good personal protection. Wear appropriate protective clothing, gloves, and protective glasses or masks to avoid direct contact with the substance with the skin, eyes and respiratory tract. If you accidentally come into contact with the skin, you should immediately rinse with a large amount of flowing water; if it splashes into the eyes, rinse quickly with a large amount of water and seek medical attention in time. Operate in a well-ventilated environment, preferably in a fume hood to prevent volatile gases from being inhaled into the body. The equipment used to access the substance must be clean and dry to prevent impurities from mixing and affecting its properties. After use, the remaining substances should be properly disposed of in accordance with regulations and should not be discarded at will to avoid pollution to the environment. During operation, the established operating procedures and safety manuals must be strictly followed, and the operation steps must not be changed without authorization to ensure the safety of the use process.
