0.38 mmoles of the compound 4-[(10-benzyl-9,10-diazatricyclo[4.2.1.12,5]-dec-9-yl)-(3-methoxyphenyl)methyl]-N,N-diethylbenzamide obtained in Example 4.1 were mixed with palladium at 10% by weight on carbon (0.1 equivalents) in ethanol (5 ml). The mixture was submitted to hydrogenation at a pressure of 45 psi of H2 and at a temperature of 60° C., for 6 hours. At the end of the reaction the catalyst was removed by filtration under vacuum. The solvent was then evaporated under vacuum obtaining the compound 4-[(9,10-diazatricyclo[4.2.1.12,5]dec-9-yl)-(3-methoxy phenyl)methyl]-N,N-diethylbenzamide. Yield: quantitative.
