In a suitable reaction vessel, 5.40 grams (0.0220 mole) of N-t-butyl anilino dimethyl sulfonium chloride was dissolved in 50 ml of dry methanol; 4.86 grams (0.0220 mole) of silver trifluoroacetate was dissolved in 50 ml of dry CH3OH and added to the sulfonium salt solution over a period of about 3 minutes. Upon commencement of the addition of the trifluoroacetate solution, a white precipitate formed. After 2 hours at room temperature, the AgCl was filtered off, and CH3OH removed by rotatory evaporation. This procedure yielded a reddish-brown oil which was triturated with dry ether to yield a white salt. This salt was dried to yield 5.43 grams (0.0168 mole) of N-t-butyl anilino dimethyl sulfonium trifluoroacetate for a 76% yield.
