실험 절차

780 ml (6.1 moles) of trimethylchlorosilane were added with vigorous stirring over 2 hours to a mixture of 400 g (4 moles) of succinimide, 900 ml (6.5 moles) of triethylamine and 2700 ml of toluene and the mixture was refluxed with stirring for one hour and was then cooled to room temperature. The mixture was filtered and the filter was washed with one liter of toluene and one liter of petroleum ether (b.p = 40°-60° C). The combined filtrate and washings were concentrated to 700 ml and then distilled at reduced pressure to 573 g (3.4 moles -- 84% yield) of N-trimethylsilyl succinimide with a boiling point of 62° C at 0.33 mm Hg.
