Reaction Steps
In 100 mL of acetonitrile, 25 g of a liquid of 1,1,2,2-tetrafluoro-4-hydroxybutanesulfonyl chloride (purity: 99%, equivalent to 0.102 mol) was dissolved by stirring. The resulting solution was cooled to 0° C., admixed with 10.3 g (0.123 mol) of sodium hydrogencarbonate and 18.3 g (0.112 mol) of N-hydroxyphthalimide, and then, reacted at 0° C. for 24 hours. To the thus-obtained reaction solution, 125 mL of water was added. The reaction solution was subsequently extracted twice with 100 mL of ethyl acetate. The resulting organic layer was washed twice with 100 mL of water and subjected to concentration. With this, 26.4 g of the target compound was obtained as a pale yellow solid (yield: 57%, purity: 82%, pure content: 21.6 g).
