Yield: 80%
Reaction Conditions:
with aluminum (III) chloride;1,4-diazabicyclo [2.2.2] octane-1,4-diium-1,4-disulfinate;sodium hydrogencarbonate in water;1,2-dichloro-ethane at 20 - 40;
Steps:
2 Example 2: Preparation of sodium 4-acetamidobenzenesulfinate
Under normal pressure, to a 100 mL three-necked flask with mechanical agitation,20 mL of 1,2-dichloroethane, 3.0 mmol was added successively at 20 ° CN-acetylAniline, 24.0 mmol of aluminum trichloride, 3.0 mmol of the above-mentioned self-made DABSO, and then heated to 25-40 ° C for 20-24 h. When the content of N-acetanilide in the reaction solution was less than 1% by liquid chromatography End. The post-treatment was carried out in the same manner as in Example 1 to give 0.53 g of a white solid powder of sodium 4-acetamidobenzenesulfinate in 80% yield.
