METHOD FOR SYNTHESIZING BENZENESULFONATE DERIVATIVE
Document Type and Number:
WIPO Patent Application WO/2019/095636
Kind Code:
A1
Abstract:
Disclosed is a method for synthesizing a benzenesulfonate derivative, which belongs to the technical field of compound synthesis. Formula (I) is used as a raw material and reacted with ethylene glycol or R2-OH to produce formula (II) or formula (III), wherein R1 is selected from an alkyl, H or F, and R2 is selected from allyl, propargyl or phenyl. The specific operations are: adding ethylene glycol or R2-OH and dichloromethane to a reactor, adding an organic base under stirring, then cooling to 15ºC or less, and starting to dropwise add formula (I); after addition is complete, bringing same to room temperature and continuing to stir for 0.5-1 h, and then raising the temperature and refluxing the reaction for 1-2 h; and after the reaction is complete, carrying out an de-ice treatment, layering, and dry concentration to obtain a benzenesulfonate derivative product. The synthesis method of the present invention is simple, the reaction process is mild and stable, the yield is high, and the resulting product has a high purity.
