Then, 1.90 parts of 2,2-diphenyl-4-bromobutyronitrile is added, and the mixture heated to reflux for 3.5 hours. This reaction mixture is cooled to about 60° C., whereupon 13 parts of benzene is added. The aqueous layer is separated and extracted with 15 parts of benzene. To the combined benzene extracts is added dropwise 2 parts by volume of a solution of hydrochloric acid in isopropanol. The volume of this solution is reduced by heating on a steam bath. Cooling affords a white precipitate which is washed with benzene and dried at 100° C. for about 2 hours. The resulting product, 2,2-diphenyl-4-(2-azabicyclo[2.2.2]oct-2-yl)butyronitrile hydrochloride, is obtained in approximately 76.8% yield. This product melts at about 194° - 197° C., and is represented by the following structural formula. ##STR11##
