| titleOfInvention | Method for preparing 2 ', 3'-dichloro-4-ethoxymethoxybenzanilide |
| abstract | The present invention aims to improve economics and improve yields by omitting the step of isolating 2 'and 3' dichloro-4-hydroxybenzanilide as a potassium salt and using a low-cost solvent. In the constitution, at least one polyalkylene polyol is added to the reaction mixture in the presence of an inorganic base, using an aromatic hydrocarbon as a solvent, and 2 ', 3'-dichloro-4-ethoxymethoxybenz In the preparation of the anilide, the step of isolating the raw material 2 ', 3'-dichloro-4-hydroxybenzanilide as a potassium salt can be omitted, and an expensive polar solvent such as N, N-dimethylformamide can be omitted. It is possible to use inexpensive aromatic hydrocarbons without the post-treatment loss after the completion of the reaction, and the economical efficiency can be remarkably improved, and the products 2 ', 3'-dichloro-4 Ethoxymethoxybenzanilide is characterized in that it has the effect of obtaining a good yield. |
