The synthesis method of 2-acetyl-4-methylpyridine has been known for a long time. In the past, Fang family used a number of methods to do it.
First, take 4-methylpyridine as the base and make it by acylation. Take an appropriate amount of 4-methylpyridine first, put it in a suitable container, and add a specific solvent to ensure that it is evenly dispersed. Then slowly add acylating reagents, such as acetyl chloride, etc. The reaction environment needs to be carefully regulated, and temperature and pH are all important. During the reaction, there may be violent chemical changes, so it must be closely monitored. After the acylation reaction is completed, the subsequent separation and purification should not be ignored. Distillation and extraction methods can be used to remove its impurities to obtain pure 2-acetyl-4-methylpyridine.
Second, it is obtained from the pyridine derivative through a multi-step reaction. First, the pyridine derivative goes through a specific substitution reaction, and methyl is introduced at a suitable check point, and then the acetylation step is carried out. Although the steps are complicated, the structure of the product can be precisely controlled. Each step of the reaction requires precise control of the conditions, and the ratio of the reactants and the reaction time are all about success or failure. After the reaction is completed, multiple separation methods are also required to achieve the purity of the product. < Br >
