Vorschrift

While cooling 10.55 g (97.1 mmol) of chlorotrimethylsilane was dropped into a solution of 19.55 g (97.1 mmol) of (2-oxo-1-imidazolidinyl)carbamic acid, 1,1-dimethylethyl ester 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 the title compound; melting point 132.1° C.
