Versuchsvorschrift

α-Phenyl-3-pyridylacetonitrile (U.S. Pat. No. 3,225,054) is reacted with 2-(2-chloroethyl)-2-azabicyclo[2.2.2]octane in toluene to provide 2-phenyl-2-(3-pyridyl)-4-(2-azabicyclo[2.2.2]oct-2-yl)butyronitrile. This nitrile is reacted with sodium azide in DMF containing lithium chloride to provide 5-[1-phenyl-1-(3-pyridyl)-3-(2-azabicyclo[2.2.2]oct-2-yl)propyl]-1H-tetrazole. Reaction this tetrazole with acetic anhydride in pyridine provides 5-[1-phenyl-1-(3-pyridyl)-3-(2-azabicyclo[2.2.2]oct-2-yl)propyl]-2-methyl-1,3,4-oxadiazole, the oxalate salt melts at 171°-172° C.
