실험 절차

First 6.3 pts. by wt. of phosgene and then 11.8 pts. by wt. of tri-n-butylamine are added to a suspension of 8.0 pts. by wt. of 1-propenyl-2-oxo-imidazolidine (prepared according to DAS (German Published Specification) No. 1,057,126) in 100 pts. by vol. of abs. ethyl acetate. The reaction mixture is stirred overnight and concentrated. The 1-chlorocarbonyl-2-oxo-3-propenyl-imidazolidine formed is used for Example 2 in a mixture with tributylammonium chloride. IR (liquid paraffin): 1,800 and 1,710 cm-1.
