Participants

Reaction Steps

While cooling, 10.55 g (97.1 mmol) of trimethylsilylchloride was dropped into a solution of 19.55 g (97.1 mmol) of 1-[(t-butoxycarbonyl)amino]-2-imidazolidinone and 9.83 g (97.1 mmol) of triethylamine in 900 ml of absolute ethyl acetate. After stirring overnight, the salt was filtered off and the filtrate evaporated in vacuo to yield 24.18 g of 1-[(t-butoxycarbonyl)amino]-3-(trimethylsilyl)-2-imidazolidinone, melting point 132.1° C.
