Reaction Conditions:

in acetone at 40 - 50; for 20 h;Solvent;

Steps:

1.a a) Preparation of β-Dimethylsulfonopropionic Acid Chloride (1)
a) Preparation of β-Dimethylsulfonopropionic Acid Chloride (1)Add 4mol 3-chloropropionic acid and 6mol dimethyl sulfide in the reaction flask, stir and heat to 40-50 ° C to dissolve the 3-chloropropionic acid in dimethyl sulfide, add 700ml of organic solvent acetone During the operation, methyl ethyl ketone or ethyl acetate may be used instead of acetone as the organic solvent), and stirring is continued for 20 hours while maintaining the temperature at 50 ° C. The mixture is cooled in a water bath to cool down to 25 ° C and suction filtered. The filter cake was recrystallized from 1000 ml of 95% (mass fraction) ethanol to obtain white crystal A, which was β-dimethylsulfonopropionate chloride, weighing 156.5 g.
