Paragraph 0039-0041, (2018/04/01)
The invention discloses a method for synthetizing 2-(methylthio)-4-trifluoromethyl ethyl benzoate. 4-fluorine-3-chlorobenzotrifluoride is adopted as a raw material, and through cyanation, methylthiolation and a hydrolytic esterification reaction, 2-(methylthio)-4-trifluoromethyl ethyl benzoate (an isoxaflutole midbody) is obtained. According to the synthetizing method, 4-fluorine-3-chlorobenzotrifluoride is adopted as the raw material, the price is low, the cost of the raw material is drastically lowered, the reaction path is simple, few byproducts are generated, the yield is high, the solventand the catalyst are both recyclable, less three-waste (waste gas, wastewater and solid waste) is discharged, the reaction condition is mild, and the synthetizing method is easily popularized to industrialized production.
