Use | thiophene-3-ethanol can be used as a pharmaceutical synthesis intermediate, which is used in the production of thienethylamine, ticlopidine, one of the raw materials of drugs containing thiophene structure such as clopidogrel. |
synthesis method | the optimum technological conditions for the synthesis of thiophen-3-ethanol by sodium metal method are as follows: the initial molar ratio of thiophene to sodium metal is 1.6: 1, the molar ratio of ethylene oxide to sodium metal is 1: 1, the epoxidation temperature is -5 ℃, the reaction time is 30min, the pH value of hydrolysis reaction was 4~6. Through the optimization of the process, the final yield of thiophene -3-ethanol can reach 84%, and the purity is as high as 99.63%. |
