실험 절차
A solution of 3-benzyl-3,8-diazabicyclo[3.2.1]octane-2,4-dione LXVI (0.00108 mol, 250 mg) in dry ether (2 mL) was added to a stirred suspension of LiAlH4 (122 mg, 0.00315 mol) in dry ether (8 mL) at 0° C. under nitrogen atmosphere. The reaction bath was allowed to return at room temperature and stirring was continued for 30 h. After completion of the reaction (checked by TLC), the reaction mixture was quenched with chilled water and then stirred for 1 h. The reaction mixture was diluted with ether (20 mL) and the organic layer was washed with water, dried over Na2SO4, concentrated under reduced pressure. The crude residue was purified by column chromatography (silica gel, 60-120 mesh; EA-Hexane, 1:1) to afford the product LXVII in 52% yield.
