There are many ways to synthesize 2-ethoxy-3-methylpyrazine. One method is to use 2,3-dimethylpyrazine as the starting material. First, when 2,3-dimethylpyrazine is encountered with strong oxidants, such as potassium permanganate, the reaction environment is adjusted, and its temperature and pressure are controlled. It can cause the methyl oxidation of 2,3-dimethylpyrazine to form a carboxyl group to obtain 2-carboxyl-3-methylpyrazine.
times, the 2-carboxyl-3-methylpyrazine is co-placed with ethanol, and an appropriate amount of concentrated sulfuric acid is added as the catalyst. Heat up to promote esterification. At this time, the carboxyl group is condensed with the hydroxyl group of ethanol, and the water is removed to form an ester bond to obtain 2-ethoxycarbonyl-3-methylpyrazine. After
, use 2-ethoxycarbonyl-3-methylpyrazine as a reducing agent such as lithium aluminum hydride. Carefully control the reaction to reduce the ethoxycarbonyl to ethoxy, and finally obtain 2-ethoxy-3-methylpyrazine.
Another method uses 2-chloro-3-methylpyrazine as a base material. When 2-chloro-3-methylpyrazine meets sodium ethanol, the chlorine atom is replaced by ethoxy, which is the response to nucleophilic substitution. When adjusting its temperature, pressure and reaction, the target substance 2-ethoxy-3-methylpyrazine can be obtained. After the reaction is completed, it can be separated and purified by ordinary methods, such as distillation, extraction, chromatography, etc., to obtain a good product.
Furthermore, it can be prepared by suitable nitrogen-containing and oxygen-containing small molecules through multi-step condensation and cyclization. However, the way is more complex, and each step of the reaction must be carefully controlled to achieve the best effect.
