To a cold (0° C.) solution of 9-benzyl-9,10-diazatricyclo[4.2.1.12,5]decane (J. Med. Chem. 2000, 43, 2115-2123) and TEA in an DMF (1-2 ml) was added MeI. The mixture was allowed to warm to rt and stirred for 2-3 h. The rxn mixture was evaporated to dryness and partitioned between ether and satd. NaHCO3 and ether layer separated, washed with brine and dried (Na2SO4). Evaporation of ether afforded 9-benzyl-10-methyl-9,10-diazatricyclo[4.2.1.12,5]decane as a light-brown oil. A stirred suspension of 9-benzyl-10-methyl-9,10-diazatricyclo[4.2.1.12,5]decane in EtOH containing conc. HCl (0.5 ml) and 10% Pd—C was hydrogenated under balloon pressure of hydrogen overnight. The suspension was filtered and filtrate was added dry toluene (10-15 ml) and evaporated to dryness to afford the 9-methyl-9,10-diazatricyclo[4.2.1.12,5]decane and isolated as bis-HCl salt.
