Ethyl 4- (Trifluoromethyl) -2-Methylthiazole-5-Carboxylate 4- (trifluoromethyl) -2 -methylthiazole-5 -carboxylic acid ethyl ester, the synthesis method is as follows:
The starting material can be selected from suitable sulfur-containing compounds, carbonyl compounds and fluorine-containing reagents.
The first step is to condensate the sulfur-containing compound and the carbonyl compound under suitable reaction conditions, usually in a base-catalyzed environment. This reaction aims to construct the basic structure of the thiazole ring. The base can be selected as a common inorganic base such as potassium carbonate. The reaction solvent is preferably a polar aprotic solvent, such as N, N-dimethylformamide (DMF). The reaction temperature is controlled within a certain range, generally at 60-80 ° C, and the reaction time is about several hours. The two fully react to form a preliminary thiazole ring intermediate.
The second step is to introduce a trifluoromethyl group for the generated thiazole ring intermediate. Special trifluoromethylation reagents can be used, such as sodium trifluoromethylsulfonate, etc. In a specific reaction system, this reagent undergoes a nucleophilic substitution reaction with the intermediate to introduce trifluoromethyl into a suitable position of the thiazole ring. This step requires controlling the reaction conditions, such as temperature, reaction time, and the dosage ratio of reagents. The temperature may be 50-70 ° C. The reaction time is adjusted according to the specific situation to ensure the accurate introduction of trifluoromethyl and fewer side reactions.
The third step is to carry out the esterification reaction. The thiazole ring product containing trifluoromethyl is esterified with ethanol under acid catalysis. The commonly used acid catalysts are concentrated sulfuric acid or p-toluenesulfonic acid. Under the condition of heating and reflux, the general temperature is 80-100 ° C. The reaction takes several hours to promote the esterification reaction of carboxylic acid and ethanol, thereby generating Ethyl 4- (Trifluoromethyl) -2-Methylthiazole-5-Carboxylate. After the reaction, the product is purified by conventional separation and purification methods, such as extraction, distillation, column chromatography, etc., to obtain high-purity target products.
