실험 절차
A three neck 3 L flask, fitted with a well isolated soxhlet (300 mL) filled with molecular sieves (3 Å), was charged with 5-amino-bicyclo[2.2.2]octan-2-one trifluoro-acetic acid salt (Preparation 76, 85.0 g, 336 mmol, 1.0 eq), benzaldehyde (37.5 mL, 369 mmol, 1.1 eq) and DCM (1.25 L). The suspension was heated to reflux. The clear reaction mixture was concentrated to a tan solid. The latter was suspended in a mixture of diethyl ether (600 mL) and EtOH (50 mL). The solids were collected by filtration (P3) and thoroughly washed with ethyl acetate and diethyl ether. The filter cake was dried in vacuo to yield title compound as an off-white solid (104 g, 305 mmol, 91%, 97.3% pure (HPLC)).
