[1] Method for preparing 3,4-difluoroanisole. CN105523904A | [Synthesis]
The method for preparing 3,4-difluoroanisole includes the steps that compound 3,4-difluorophenol is dissolved in acetonitrile, potassium carbonate is weighed, methyl iodide is dripped, and the mixture is reacted overnight at an indoor temperature; thin-1ayer chromatography is carried out on the next day, and it is discovered that the raw materials are completely reacted; reaction liquid is poured into water to be fully stirred, the lower layer organic phase is separated, then dichloromethane and water are added, and full washing and separation are carried out; afterwards, washing with water is conducted twice, and the organic phase is separated, dried and subjected to atmospheric distillation; the product, dichloromethane and residual acetonitrile are azeotropic, a vacuum pump is used for conducting reduced pressure distillation from the temperature of 60 DEG C, colorless clear liquid is steamed out when the temperature is raised to 120 DEG C, and accordingly the compound 3,4-difluoroanisole is obtained. |
