Reaction Steps

Reaction of 2.5 parts of diphenyl-3-pyridylmethane in 60 parts by volume of cyclohexane with an equivalent amount of butyl lithium at 10° C under nitrogen is followed by the addition of 2.1 parts of 4-(2-chloroethyl)-4-azatricyclo[4.3.1.13,8 ]undecane [preparable by mixing the hydrochloride thereof (U.S. Pat. No. 3,845,038) with excess aqueous sodium carbonate, extracting the mixture with toluene, and consecutively washing the extract with water, drying it over anhydrous sodium sulfate, filtering out the drying agent, and removing the solvent by vacuum distillation]. Quenching of the reaction with water and isolation by extraction with ether, washing, drying and evaporation of solvent provides 4-[3,3-(diphenyl)-3-(3-pyridyl)propyl[-4-azatricyclo[4.3.1.13,8 ]undecane having the following structural formula ##STR52##
