Reaction Conditions

Reaction Steps

230 Parts of 30% aqueous sodium hydroxide solution was added into a mixture of 100 parts of methyl difluoro(fluorosulfonyl)acetate and 250 parts of ion-exchanged water in a ice bath. The added mixture was heated and refluxed at 100° C. for 3 hours. After cooling, the cooled mixture was neutralized with 88 parts of conc. hydrochloric acid and concentrated to obtain 165.0 parts of sodium difluorosulfoacetate (containing inorganic salt, purity: 62.5%).
