Reaction Steps

9-(4-Methylbenzyl)-9-aza-bicyclo-[3.3.1]-nonan-3-one oxime (4 g) was dissolved in amyl alcohol (100 ml) and heated to reflux. Sodium (2 g) was added portionwise whilst the solution was stirred. After all the sodium had dissolved, the solution was cooled, diluted with ether and acidified with dilute hydrochloric acid. The acid extract was washed with ether and then basified with excess potassium carbonate. Extraction with ethyl acetate followed by evaporation of solvent afforded crude 3-amino-9-(4-methylbenzyl)-9-azabicyclo[3.3.1]-nonane (3.6 g, 95%) used in the next procedure without purification.
