Reaction Conditions

Reaction Steps

29.5 g of 3-(2-chloro-5-nitro-5-nitrophenylsulphonyl)propionic acid and 15 g of 1,2-diaminoethane are refluxed in 150 ml of isopropanol for two hours. The reaction mixture is cooled down to 0° C. and filtered with suction. The isolation is suspended in 100 ml of water, the suspension is brought to pH 3.5, and 15 g of sodium chloride are added for salting out. The precipitated betaine is filtered off with suction and dried. The yield of 3-[2-(-aminoethyl)amino-5-nitrophenylsulphonyl]-propionic acid is 28.5 g.
