Paragraph 0029; 0030, (2017/09/02)
The invention discloses a method of preparing intermediates of fufu grass alkone, including: (1) to between three happens b nitrile and benzene acetyl chloride as the starting material, tertiary butyl alcohol sodium and organic solvent in the presence of the intermediate obtained by reaction of (3 - trifluoromethyl-phenyl) - benzyl carbonyl - b nitriles; (2) intermediate (3 - trifluoromethyl-phenyl) - benzyl carbonyl - acetonitrile and glacial acetic acid by the reaction of bromine fufu grass alkone intermediate 2 - phenyl - 3 - oxo - 4 - (3 - trifluoromethyl-phenyl) - 5 - amino - 2, 3 - dihydrofuran. Preparation method of this invention mild reaction, after treatment is simple, safety and environmental protection, especially few by-products, the product has high purity, and thus is suitable for industrial production.
