Yield:821-48-7 100%

Reaction Conditions:

with thionyl chloride in 1,2-dichloro-ethane at 50; for 3 h;

Steps:

1
Into a 1 L flask, equipped a refluxing condenser, is added 31.5 g (0.30 mole) of diethanolamine and 300 mL of dichloroethane, then 51.0 mL of thionyl chloride. Solid suspension formed immediately after the addition of thionyl chloride and then dissolved upon warming to 50° C. During refluxing, the solid suspension is dissolved and then the crystalline solid appears. The crystalline suspension is refluxed while being stirred for 3 hrs. The reaction is quenched by adding 20 mL of methanol and the solvents are removed under vacuum. A white crystalline material, bis(2-chloroethyl)amine hydrochloride, weighted 53.0 g, is obtained in a quantitative yield.
