Paragraph 0020; 0021, (2019/04/30)
The invention discloses a method for preparing a S-(-)-Benzoylthio-2-methylpropanoic acid compound. S-(-)-3-acetylthio-2-methylpropionic acid as a raw material shown in the formula II is hydrolyzed ina reacting solvent to obtain S-(-)-3-mercapto-2-methylpropionic acid shown in hte formula III, and the S-(-)-3-mercapto-2-methylpropionic acid and benzoyl chloride are subjected to condensation to obtain the S-(-)-Benzoylthio-2-methylpropanoic acid shown in the formula I. The preparation method is easy in operation, the raw materials and accessory materials are low in cost and easy to obtain, thereaction conditions are mild, the yield is high, and the quality is high. (The formula is shown in the description.).
