Reaction Steps
A mixture of 15.8 parts β-hydroxy-phenethyl-amine, 13 parts 2-nitramino-2-imidazoline and 8 parts xylene is stirred and heated for 30 minutes at 160°C. (oil-bath). After cooling the reaction mixture to a temperature of about 70°C., there are added 40 parts acetone. The whole is filtered warm and after cooling the filtrate to room temperature, the precipicated product is filtered off and dried, yielding 2-(β-hydroxy-phenethyl-amino)-2-imidazoline; m.p. 147°-149°C.
