Reaction Steps

A three-necked round bottom 500 mL flask fitted with a stirrer, heating mantle, condenser, nitrogen inlet, Dean-Stark trap and thermometer was charged with [C4F9SO2N(CH3)CH2]2CHOH (204.6 g, 0.300 mol), and methyl ethyl ketone (250 g). The mixture was heated and approximately 50 g of material was removed using the Dean-Stark trap. The mixture was cooled to 30° C., and OCN(CH2)3Si(OCH2CH3)3 (74.4 g, 0.301 mol) and three drops of stannous octanoate were added. The mixture was heated at 75° C. under nitrogen for 16 hours. A clear, slightly yellow product ensued. Analysis of the product was consistent with [C4F9SO2N(CH3)CH2]2CHOC(O)NH(CH2)3 Si(OCH2CH3)3.
