-

Yield:60319-09-7 90%

Reaction Conditions:

with sodium carbonate in toluene at 5 - 20; for 8 h;

Steps:

1.1

(1), 3,5-dimethoxyphenol (0.8mol, 123.3g), Sodium carbonate (0.8mol, 84.8g),Toluene (500mL) was added to a 1L four-necked flask,Stir well,Cool down to 5,Start slowly adding trifluoromethanesulfonyl chloride (0.8mol, 134.8g) dropwise,After the addition, the temperature was raised to 20°C and the reaction was stirred for 8h.After the reaction, it was cooled, washed with water until the organic phase was neutral, the water phase was separated, and the organic phase was distilled under reduced pressure to recover the solvent to obtain a colorless liquid as 3,5-dimethoxyphenyl trifluoromethanesulfonate (205.9 g), the yield is 90%;
