実験手順
Bis(2-chloroethyl)amine hydrochloride (5 g, 0.028 mol) is put into a 100 mL two-necked flask, and N,N′-Dimethylpiperazine (7.1 eq) is added into the flask. After cooling the flask and the reactants therein to about 4° C., POCl3 (4.49 g, 1.04 eq) is slowly dropped into the flask, and the mixture in the flask is stirred at room temperature for 5 hours. After that, the mixture in the flask is cooled to about 4° C., and 3-aminopropanol (2.1 g, 1.0 eq) is slowly dropped into the flask for 3 hours. After adding 3-aminopropanol into the flask, the mixture in the flask is stirred at room temperature for 15 hours. (The conversion yield determined with HPLC is about 11.84%.)
