Reaction Steps
To 2.18 ml of chlorosulfonyl isocyanate in 10 ml of dichloromethane is added dropwise, at 0° C., a solution of 1.77 ml of bromoethanol in 10 ml of dichloromethane. The reaction medium is stirred for 10 minutes at 0° C. and then added dropwise to a solution of 4.38 grams of bis(trimethylsilyl)methylamine and 3.51 ml of triethylamine in 40 ml of dichloromethane at 0° C. After warming to 20° C. and stirring for 4 hours, the reaction mixture is cooled to 0° C. and 10.5 ml of triethylamine are then added dropwise. The reaction mixture is then stirred overnight at room temperature. It is then diluted with dichloromethane and washed 3 times with dilute hydrochloric acid. The organic phase is then washed once with saturated aqueous NaCl solution and then dried over sodium sulfate and concentrated under reduced pressure to give a white solid, 2-oxooxazolidine-3-sulfonic acid [bis(trimethylsilanyl)methyl]amide (65% yield).
