Examples
Embodiment 1
[0047] Add 12.12g (0.12mol) of triethylamine, 100ml of toluene and 12.5g (0.1mol) of N-methyl-o-fluoroaniline into a four-necked reaction flask, raise the temperature to 60°C, and slowly add 38.4g (0.12mol) of acid chloride, Mixed solution with 50ml of toluene, about 1 ~ 2h to complete the dropwise addition. After the dropwise addition, the mixture was incubated for 6 hours and the content of N-methyl-o-fluoroaniline was less than 1% by liquid phase detection. Toluene was removed under reduced pressure, and water was added to cool and filter to obtain compound 1-1-a-1.
Embodiment 2
[0049] Add 15.9g (0.12mol) of sodium carbonate, 100ml of toluene, and 12.5g (0.1mol) of N-methyl-o-fluoroaniline into a four-necked reaction flask, raise the temperature to 60°C, and slowly add 38.4g (0.12mol) of acid chloride, and The mixed solution of 50ml toluene was added dropwise in about 1-2 hours. After the dropwise addition, the mixture was incubated for 6 hours, and the content of N-methyl-o-fluoroaniline was detected by the liquid phase to be less than 1%, the toluene was removed under reduced pressure, and the compound 1-1-a-2 was obtained by cooling and filtering by adding water.
Embodiment 3
[0051] The difference between this example and Example 1 is that the solvent used in the example is ethylene dichloride.
