Procedure

3-aminopropanol (2.1 g, 0.028 mol) and N-methylmorpholine (12.9 eq) are placed into a three-necked flask and stirred at room temperature. After cooling the mixture in the flask, POCl3 (4.3 g, 0.028 mol) is slowly dropped into the mixture. After adding POCl3, the mixture in the flask is stirred at room temperature for 15 hours. After that, bis(2-chloroethyl)amine hydrochloride] (5 g, 0.028 mol) is added into the mixture in the flask. The mixture in the flask is heated to about 40° C. and stirred for 6 hours. (The conversion yield determined with HPLC is about 10.0%.)
