Procedure

A mixture of 2.07 g of 2,2-diphenyl propionitrile and 2.78 g of ethylenediamine.tosylate was heated at 200° C. for 3 hours. After cooling, the solution was rendered basic with an alkali hydroxide and extracted with chloroform. The chloroform layer was washed with water and dried. After evaporating chloroform, the resulting residue was recrystallized from a mixture of benzene and hexane to give 1.4 g of 2-(2,2-diphenyl ethyl)-2-imidazoline having a melting point of 98° to 101° C. The hydrochloride thereof had a melting point of 173°-175° C.
