Versuchsvorschrift

The N-ethanesulphonyl-imidazolidin-2-one was then suspended in dichloromethane, a large excess of phosgene was introduced at 0°C, a little pyridine was added and the mixture was left to stand overnight. The excess phosgene was then largely removed by passing in dry air and the product (3-ethanesulphonyl-imidazolidin-2-on-1-carbonyl chloride) was suspended in dichloromethane and filtered off.
