The mixture was filtered, evaporated in vacuo, dissolved in dilute hydrochloric acid, basified and extracted into ethyl acetate. The combined organic layers were dried (K2CO3), filtered and evaporated in vacuo to yield 3 -amino-9-methyl-9azabicyclo-[3.3.1]-nonane (2.67 g., 90%), used without further purification.
