Paragraph 0023, (2016/10/10)
The invention discloses an efficient method of producing herbicide [...], to trifluoromethyl benzene b nitrile and benzene acetic acid ethyl ester as the main raw material, the claisen condensation, cyclization under in an acidic solvent, methylation three steps [...] the target product can be obtained. The present invention has higher safety, for reaction and purification conditions is relatively low, it is relatively easy to separate, and is not easy to generate discharge of waste acid, the solvent can be recycled, the production yield is higher. This method is more suitable for the industrial production of [...], [...] is more favorable for the wide application of efficient herbicide. (by machine translation)
