Participants

Reaction Steps

Added to a solution of 1,2-dichloroethane (20 ml), containing the PhSCF2CF2SO2F (2.09 g, 7.2 mmol) obtained according to the method from example 3, was freshly distilled benzylamine (4 ml, 37 mmol). The mixture was stirred and heated at 50° C. for 20 h until the disappearance of PhSCF2CF2SO2F (monitored by TLC and 19F NMR/CDCl3). After returning to ambient temperature, an aqueous solution of HCl (10%) was added to the reaction medium. The aqueous and organic phases were separated and the aqueous phase was extracted with dichloromethane. The organic phases were combined and dried over MgSO4. After filtration and evaporation of the solvents, the residue was purified by chromatography over silica gel (pentane to pentane/AcOEt:4/1). The sulfonamide product was obtained in the form of a white solid (2.1 g, 77%).
