Reaction Steps

50.21 g (100.0 mmol) of perfluoroctanesulfonyl fluoride is added in drops to a mixture of 10.62 g (105.0 mmol) of triethylamine and 10.12 g (100.0 mmol) of benzylamine at 80° C. while being stirred vigorously. It is stirred for 2 days at 80° C., the reaction mixture is mixed with 300 ml of water and extracted three times with ethyl acetate. The combined organic extracts are dried on sodium sulfate, filtered and concentrated by evaporation. The residue is chromatographed on silica gel (mobile solvent: dichloromethane/methanol=4/1).
