Reaction Steps

3.5 g 3-cyclopropylmethyl-9,9-dimethyl-3,7-diazabicyclo[3,3,1]nonane were dissolved in 25 ml dimethylformamide, and 0.8 g lithium amide were added to the solution. The reaction mixture was then maintained at a temperature of 60° C. for one hour and subsequently allowed to cool. After cooling, a solution of 8 g bis-(4-fluorophenyl)methyl chloride in 10 ml dimethylformamide was added in drops, and the reaction mixture was stirred for a further 4 hours at 40° C. Then aqueous citric acid solution was added to the reaction mixture, and the mixture was worked up as described in Example 1. 5.8 g 7-[bis-(4-fluorophenyl)methyl]-3-cyclopropylmethyl-9,9-dimethyl-3,7diazabicyclo[3,3,1]nonane were obtained as an oleaginous base.
