실험 절차
In dry benzene (50 ml), ethyl 2-hydroxyimino-2-cyanoacetate (7.2 g) and triethylamine (7.0 ml) are dissolved, and the resulting solution is dropwise added to a solution of phosgene (0.05 mol) in benzene (52.5 ml) at 5°C. The mixture is stirred at the same temperature for 2 hours and allowed to stand at room temmperature over night to give a solution of ethyl 2-chlorocarbonyloxyimino-2-cyanoacetate.
