An improved method for the synthesis of 4-azatricyclo [5.2.2.04,8] undecan-11-one (1) is reported. The synthesis involves hydrogenolysis of 8-hydroxyethyl-2-azabicyclo [3.3.1] nonan-7-one 3 followed by intramolecular alkylation of the resulting secondary amine 7. The required azabicyclic alcohol 3 was obtained by oxidative cyclization with mercuric acetate of the α-alkylated methyl 4-piperidineacetoacetate
