To a solution of 3-tert-butyl 7-hydroxymethyl-3-azabicyclo[3.3.1]nonane-3-carboxylate (7.78 g) in methanol (76 mL) was added 4M hydrogen chloride/ethyl acetate solution (76 mL). The reaction mixture was stirred at room temperature for 4 hr, and the solvent was evaporated under reduced pressure. The residue was dissolved in methanol (50 mL), and Amberlyst A-21 was added. The mixture was stirred at room temperature for 20 min, and the solid was removed by filtration. The solvent was evaporated under reduced pressure, and the residue was recrystallized from ethanol/ethyl acetate to give the title compound (5.22 g).
