The method of synthesizing diethyl 2,4-dimethyl-1H-pyrrole-3,5-dicarboxylate is contained in ancient books, and there are many ingenious methods. The following common numbers are for reference.
First, 2,4-dimethyl pyrrole is used as the starting material. First, 2,4-dimethyl pyrrole and an appropriate amount of oxalyl chloride are added in a suitable solvent, such as anhydrous dichloromethane, at low temperature, slowly dropwise and stirred. This process requires fine control of temperature and dropwise speed to prevent side reactions from clumping. When the reaction is moderate, the esterification reaction is carried out with an alcohol, such as anhydrous ethanol, catalyzed by a base, such as potassium carbonate. When reacting, it is necessary to pay attention to the amount of alkali and the duration of the reaction to ensure that the reaction is complete.
Second, 2,4-dimethyl-3,5-dicyanopyrrole can also be used as a starting material. First, it is hydrolyzed in a dilute acid solution, such as dilute sulfuric acid, by heating to convert the cyano group into a carboxyl group. In this hydrolysis process, the temperature and the concentration of the acid are the key, and must be precisely controlled. Then, ethanol and concentrated sulfuric acid are co-heated to carry out esterification reaction. The amount of concentrated sulfuric acid needs to be appropriate, too much will easily lead to side reactions such as carbonation, and too little will slow down the reaction rate.
Third, acetylacetone and diethyl malonate are used as raw materials. The condensation reaction occurs in the alkaline environment of sodium alcohol, such as the ethanol solution of sodium ethanol. During the reaction, the anhydrous degree of the solvent and the activity of the base all affect the reaction process. After the intermediate product is formed, the target product can be obtained through steps such as cyclization and dehydration. In this path, the convergence of reaction conditions at each step is extremely important and must be fine-tuned according to the experimental results.
All the above methods have their own advantages and disadvantages. When operating, it is necessary to make a careful choice according to the actual situation, such as the availability of raw materials, cost, equipment conditions, etc., in order to efficiently synthesize diethyl 2,4-dimethyl-1H-pyrrole-3,5-dicarboxylate.
