反応手順
160 g of 10% strength sodium hydroxide solution were added to 40.1 g (0.4 mol) of 2-chloroethylamine hydrochloride, dissolved in 150 ml of water, and 22.2 g (0.1 mol) of dichloromaleic acid dichloride were then introduced slowly at room temperature. The product which precipitated was filtered off and dried. 19.7 g of dichloromaleic acid bis-(2-(chloroethyl)-amide of melting point 107°-110° C. were obtained, that is to say 64% of theory.
