Procedure

N-benzyl-3-azabicyclo[3.3.1]nonane-9-one (28) was synthesized according to a method described in J. Med. Chem. 1994, 37, 2831-2840. Sodium borohydride (1.49 g) was added into the MeOH (80 ml) solution of (28) (6.75 g) with chilling on ice. After its mixture was stirred for 1 hour with chilling on ice, its solvent was evaporated under reduced pressure. Water was added to its residue, which was then subjected to extraction with methylene chloride, followed by drying its organic layer with anhydrous magnesium sulfate. Its solvent was evaporated under reduced pressure to produce a crude compound (29) (6.52 g).
