Phosgene → 2-oxo-3-phenylimidazolidine-1-carbonyl chloride

Participants

Reaction Steps

16.2 parts by wt. of 1-phenyl-2-oxo-imidazolidine were suspended in 160 parts by vol. of tetrahydrofurane and 12.0 parts by wt. of phosgene, dissolved in 30 parts by vol. of tetrahydrofurane, were added dropwise at 10° C. The mixture was then stirred for a further 4 hrs. at 10° C and left to stand overnight at 20° C, and the precipitate present was then filtered off, washed with tetrahydrofurane and dried.
