The Production Process of ETHYL 2-CHLORO-4-(TRIFLUOROMETHYL)PYRIMIDINE-5-CARBOXYLATE

Ethyl 2-chloro-4-(trifluoromethyl)pyrimidine-5-carboxylate is an important intermediate in the production of various pharmaceuticals, agrochemicals, and other chemical products.
The production process of this chemical involves several steps, which are described below in detail.

1. Begin by preparing a solution of 2-chloro-4-(trifluoromethyl)pyrimidine in a solvent such as acetonitrile or water.
   The concentration of the solution should be around 1-10% by weight.
   
2. Next, add sodium hydroxide to the solution in small portions, stirring continuously.
   The amount of sodium hydroxide used should be carefully controlled to avoid excessive hydrolysis of the pyrimidine.
   
3. After adding the sodium hydroxide, the reaction mixture should be stirred for several hours at room temperature or overnight at 4-5°C.
   The reaction is complete when the pH of the solution reaches 7-8.
   
4. The reaction mixture is then acidified using hydrochloric acid, which causes the formation of the carboxylate salt.
   The pH of the solution should be monitored during this step to ensure that it reaches the desired value.
   
5. The resulting salt is then filtered, washed with water, and dried.
   The product can be further purified by recrystallization or other methods.
   
6. The purified ethyl 2-chloro-4-(trifluoromethyl)pyrimidine-5-carboxylate is then used as a starting material for further chemical transformations, such as oxidation or reduction reactions, to produce the desired product.
   

The production process of ethyl 2-chloro-4-(trifluoromethyl)pyrimidine-5-carboxylate involves several steps, including the preparation of the substrate, the hydrolysis reaction, the formation of the carboxylate salt, and the purification of the product.
