To a vigorously stirring suspension of (6S)—N-benzyl-2-azabicyclo[2.2.2]octan-6-ol (1.5 g, 6.9 mmol, Maybridge) and activated 4 Å MS (1.0 g) in acetonitrile (70 mL) at 23° C. was sequentially added 4-methylmorpholine-N-oxide (1.2 g, 10 mmol) and tetrapropylammonium perruthenate (240 mg, 0.69 mmol). After stirring the resulting black suspension for 30 min, the mixture was concentrated in vacuo, and the resulting residue was purified by flash chromatography (20-50% ethyl acetate in hexanes) to provide N-benzyl-2-azabicyclo[2.2.2]octan-6-one as an orange oil (1.2 g, 81%). MS (AP CI) 216 (M+H).
