Participants

Reaction Steps

bis(2-Chloroethyl)amine hydrochloride (Tokyo Chemical Industry CO., LTD., 3.0 g) was dissolved in acetone (50 ml), potassium carbonate (3.0 g) and ethyl chloroformate (2.4 ml) were added, and the mixture was heated under reflux for 4 hr. After completion of the reaction, the mixture was cooled to room temperature, and the solid was filtered off.
